Let "power exchange" be included in the eyes of supervision


Original title: Let "power exchange" be included in the eyes of supervision

"Power exchange" is to supplement the electric energy by directly replacing the vehicle battery. In recent years, there are more and more battery changing cabinets and power changing stations for electric bicycles and electric vehicles on the streets of Wuhan, which are favored by many people because they can quickly replenish battery life. Recently, relevant departments are exploring the new format of "power exchange" and bringing it into the eyes of supervision.

Late at night, the streets "exploded" with security risks.

At 11 o’clock on the evening of March 26th, a loud noise broke the silence of the night in Taipei Street, Jiang ‘an District, Wuhan.

An explosion occurred in a battery changing cabinet in this area, and the cabinet door was damaged and deformed by the explosion shock wave, and the display was seriously damaged. The accident was caused by abnormal internal communication in the battery management system, resulting in high temperature, thermal runaway of the battery core, rapid rise of internal temperature, opening of battery pressure relief, and high-temperature electrolyte mixed gas leaked from the battery core entering the warehouse, which led to the explosion of the warehouse body. Fortunately, when the accident happened, no pedestrians passed near the switchboard, causing no casualties.

"Compared with the switchboard, the switchboard is more dangerous, and once an accident occurs, the consequences are unimaginable." Zhao Junke, the comprehensive supervision department of Jiang ‘an District Emergency Management Bureau, said that after the explosion of the power exchange cabinet, they immediately carried out the investigation and management of potential safety hazards for the electric vehicle power exchange station, which belongs to the new format of "power exchange".

On April 8, when the law enforcement officers of Jiang ‘an District Emergency Management Bureau conducted safety inspection on two power stations in the jurisdiction, they found that the two power stations had problems such as loose management, undisclosed personnel qualifications, incomplete inspection and maintenance records of facilities and equipment, and failure to report to the fire department in the jurisdiction.

On April 19th, a fire broke out in a taxi-changing power station in Shijingshan District, Beijing. The Beijing Shijingshan Fire Rescue Detachment announced that the fire fighting operation continued until 0: 30am on the 20th, and 17 fire engines and 85 firefighters were dispatched. Two lithium batteries used for replacing electricity in taxis were burned at the scene.

Explore and clarify the regulatory responsibility of "changing electricity"

"Changing power stations and cabinets is a new thing. We are all amateurs and it is not good to tell us what to do." Zhao junke said. The lack of new energy-related knowledge reserves makes it difficult for them to comprehensively supervise the power station, but the deeper reason is that the subject of supervision responsibility is not clear.

The Law of People’s Republic of China (PRC) on Work Safety provides guidance for the centralized responsibility work. At present, there is a "quasi-mother-in-law" who supervises the Weilai automobile exchange power station in Jiang ‘an District. Weilai Power Station had previously issued a filing certificate to Jiang ‘an District Emergency Management Bureau, which showed that the project was introduced and approved by Jiang ‘an District Development and Reform Bureau. According to the principle of "whoever is in charge is responsible" and "whoever approves is responsible" in "People’s Republic of China (PRC) Law on Work Safety" and "Fifteen Measures for Work Safety of the State Council Safety Committee", Jiang ‘an District Emergency Management Bureau believes that Jiang ‘an District Development and Reform Bureau should bear the main supervision responsibility for Weilai Power Station. At present, the opinions on the revision of the safety production supervision responsibilities of the member units of the Safety Committee have basically taken shape.

The supervision of Weilai Power Station can be smoothly promoted because the relevant procedures are approved by the same level department of Jiang ‘an District Emergency Management Bureau. However, the main responsibility of the supervision of the "power exchange" project approved by non-peer departments is still being explored.

Grassroots call for a clear division of regulatory responsibilities

For example, Zhao Junke said that there are more and more battery "changing cabinets" on the streets of Wuhan. Among them, most of the battery changing cabinets for electric bicycles built by China Tower Energy Hubei Co., Ltd. based on tower base stations mainly provide battery replacement services for take-away riders.

"The approval department for the relevant procedures of the switchboard is the Hubei Provincial Development and Reform Commission, and the Jiang’ an District Emergency Management Bureau is the grassroots emergency management department. We can only report the situation to the higher authorities and wait for the higher authorities to discuss the results." Zhao junke said.

With the rapid development of China’s social economy, in recent years, overlapping functions and new formats have emerged, which has become a "blind spot" for safety supervision. She Zhenglin, member of the Party Committee and deputy director of the Jiang ‘an District Emergency Management Bureau, said: "The main units responsible for the new format belong to different regulatory departments. To effectively supervise the new format, it is necessary to improve the top-level design."

"At the beginning of the introduction of such new formats, the top-level design should be done well, and the responsibility package should be clearly divided. The supervision of new formats by grassroots regulatory authorities will be much more efficient." Zhao Junke said frankly.

Interpretation by the National Bureau of Statistics: China’s R&D investment has reached a new level of 3 trillion yuan.

  Cctv newsAccording to the website of the National Bureau of Statistics, the latest data of the National Bureau of Statistics show that in 2022, the total social research and experimental development (R&D) funds in China will continue to maintain double-digit growth, and the total investment will reach a new level of 3 trillion yuan; The investment intensity of R&D funds increased rapidly, reaching a new height of 2.5%.

  1. R&D funds grew steadily, exceeding 3 trillion yuan for the first time.

  In 2022, due to multiple unexpected factors, the R&D activities of the whole society were affected to some extent. However, the policy of adding and deducting R&D expenses of enterprises continued to increase, and the mechanism of scientific and technological awards and incentives continued to improve, effectively stimulating the innovation vitality of market players, and the R&D investment of enterprises still maintained double-digit growth, driving the total R&D investment of the whole society to a new level. According to preliminary calculations, in 2022, China’s R&D investment reached 3,087 billion yuan, which exceeded the 3 trillion mark for the first time, up by 10.4% over the previous year, and has maintained double-digit growth for seven consecutive years since the Thirteenth Five-Year Plan. Calculated at constant prices, R&D expenditure increased by 8.0%[1], which was higher than the target of "the total social R&D expenditure increased by more than 7% annually" in the Tenth Five-Year Plan.

  Second, the investment intensity increased rapidly, reaching a new level of more than 2.5%.

  According to preliminary estimates, in 2022, the investment intensity of R&D funds (the ratio of R&D funds to GDP) in China reached 2.55%, reaching a new high, with an increase of 0.12 percentage points over the previous year [2], which was significantly higher than the average annual growth rate (0.07 percentage points) since the Thirteenth Five-Year Plan, and achieved rapid improvement. From the international comparison [3], China’s R&D expenditure intensity ranks 12th among the major countries in the world, surpassing innovative countries such as France (2.35%) and the Netherlands (2.32%), and further approaching the average level of OECD countries (2.67%). According to the Global Innovation Index (GII) released by the World Intellectual Property Organization in 2022, China’s scientific and technological innovation performance ranked 11th among 132 economies, up one place from the previous year. Since 2013, China’s ranking has increased by 24 places, and it has maintained a steady upward trend for 10 consecutive years.

  Third, basic research has maintained growth and new breakthroughs have been made in original innovation.

  According to preliminary calculations, in 2022, China’s basic research expenditure was 195.1 billion yuan, an increase of 7.4% over the previous year; The proportion of R&D funds was 6.32%, down 0.18 percentage points from the previous year, but it was still at the second highest level in history, and remained above 6% for four consecutive years, which played a positive role in the continuous improvement of China’s original innovation capability. The state attaches great importance to basic research. In 2022, the expenditure on basic research in the budget of the central government at the corresponding level increased by 7% compared with the previous year. The construction of national laboratories and the reorganization of national key laboratories were accelerated, and the research center for basic disciplines was started. A series of new major breakthroughs were made, such as the national major scientific and technological infrastructure "steady-state strong magnetic field experimental device" to create a steady-state strong magnetic field with a field strength of 452,200 gauss.

  Despite the multiple adverse factors, China’s R&D investment continues to grow steadily, which has injected great vitality into innovation and development. However, we should also see that there is still a big gap between us and the requirements of accelerating the construction of a strong country in science and technology and realizing self-reliance and self-improvement in high-level science and technology. In the next step, we should fully implement the spirit of the 20th Party Congress, adhere to the orientation of self-reliance and self-improvement in science and technology policies, encourage and guide all parties to increase investment in R&D, especially in original innovation, and strive to promote the transformation of R&D investment from "big" to "strong", so as to provide strong support for the construction of a strong country in science and technology.

  Note:

  [1] Except here, the growth rate of other indicators in this paper is the current price growth rate.

  [2] According to the final revision of GDP in 2021 by the National Bureau of Statistics, the investment intensity of R&D funds in 2021 was correspondingly revised to 2.43%.

How to start the drama comprehensive market in 2024 when the "flowers" are exhausted?

Wen | Ruopu

Blossoms Shanghai, which was launched with high fever at the end of the year, drew a satisfactory conclusion for the entertainment market in 2023, and also made the public have new expectations and pursuits for the audio-visual content in the new year. In this context, how does the entertainment market arrange its troops in content to meet the higher needs of users? Here, I read the comprehensive map of the drama in January, from which I can also find some new industry trends.

Blossoms Shanghai, who focused on Shanghai’s development wave in the 1990s, just finished, followed by "Years Like Songs", which focused on the economic wave in the 1990s, and "Love for a long time", which was set in the 1990s and told the story of seven only children in the North Aerospace Family Courtyard, which presented the humanistic features from different perspectives in the 1990s. Judging from the current broadcast effect, the former scored 8.5 points, which is a rare word-of-mouth drama, while the latter has a good popularity.

Returning to the reality level, the urban theme characterized by differentiated painting styles and concentrated layout is still the main support of the drama market in January. From the urban drama "You also have today" and "There are many stories in a small town", to the inspirational cure "If running is my life", and then to "Our Translator" featuring "double A", we can enrich the content layout of realistic dramas with diverse plot styles, and at the same time avoid users’ aesthetic fatigue.

The final result is gratifying-"If running is my passion for life" broke 8500 in the iQiyi station, and "Our Translator" broadcast by the network ranked first in the ratings list of csm71 Satellite TV Golden Theater TV series for many times.   

Xianxia circuit was contracted by IP of "Legend of the Sword and the Chivalrous Man" series. Specifically, there are three series of fairy sword works, namely, Pray for the Present (adapted from the domestic stand-alone game Legend of the Fairy Sword and the Chivalrous Man 6) and Fairy Sword 4, which were launched on Tencent Video and iQiyi respectively, and three series of fairy sword works, Legend of the Fairy Sword and the Chivalrous Man, chinese paladin 3 and Fairy Sword Clouds, were broadcast free of charge in Youku within a limited time, which constituted "Fairy Four, Fairy Six Fight, Fairy" This new and old Xianjian IP has attracted many loyal fans to follow the drama, and the final evaluation is mixed. It remains to be seen who will laugh at the end.

Take different drama elements as the incision, and innovate the opening way of suspense drama. Or featuring the fantasy of ancient costumes, The Apocalypse combines the ancient fantasy book Shan Hai Jing with the western Cthulhu culture to refresh the public’s understanding of Chinese suspense dramas; Or taking the investigation of a single case as the main line, the suspense criminal investigation drama "Black Soil Silent" was called the Northeast version of The Knockout by fans, which became another footnote of the Northeast film and television drama; Or take the once-popular infinite flow as the plot fulcrum, 19th Floor tells the story that college students such as Chun Yu and others are involved in the game named 19th Floor with a suspenseful and adventurous style.

In addition, there are dramas with different themes, such as the anti-US aid Korea drama "Reconnaissance Hero" and the romantic drama "The Past" of the Republic of China, which are also popular on the TV platform, and also have good attention among the target audience.

Under the shadow of Blossoms Shanghai’s afterheat, the drama market in January started with high-quality dramas such as "The Years of Great Rivers are Like Songs" and "Black Soil is Silent". From the current point of view, although there is still room for improvement in terms of content reputation and popularity, it is fortunate that there are a variety of drama types and the basic calculation of the overall market is stable, as The Knockout did at the beginning of last year. Perhaps, for the platform, the next "Flowers" and "Hurricane" are already on the way.

Looking back at the variety market in January, the satellite TV platform is mainly based on the classic N-generation programs, such as Southeast Satellite TV, Jiangsu Satellite TV, Hunan Satellite TV and Beijing Radio and Television Station, which respectively launched the talk show "One Day in Luyu" in the 12th season, the brain sports reality show "super brain" in the strong return of international competitions in the 11th season, and the star-element combined music variety show "I want to sing with you" with the key words, and the documentary observation.

It is worth noting that Pang Bo served as the convener of the China team in the eleventh season of super brain, and with the super-fast problem-solving speed, the topic that # Pang Bo is worthy of having three lines of code in space #, # Pombo and super brain are in granularity alignment # caused a heated discussion. As for the video platform, the annual variety "Mao Xuewang" is the representative of the N generation, and it will be launched in the winter season at the end of this month, and will continue to tell the real and interesting stories between Mao Bu, Li Xueqin and their friends in "Mao Xuewang’s Home".

In addition to the classic trump card, the new "comprehensive 2 generation" began to emerge in the variety market in the new year. CCTV, Dragon TV, Zhejiang Satellite TV and Mango TV respectively launched a large-scale cultural program "Poetry and Painting China 2" with the theme of rivers, a happy sharing show "Open Wheat Tonight 2", an interesting variety show "Jia Kang Jia Nian Wei 2" with the themes of "Experience of Different Dynasties" and "Going to the New Year Dinner for the Millennium", and "Village Chief Li Rui, Shi Kai and Huang Wenjin as" hometown exploration ". The second season.

Judging from the "Comprehensive Generation 2" film list, most of the content themes are biased towards the main theme. However, relatively speaking, "Open Wheat 2 Tonight" is even more out of the loop. Thanks to the guests’ bold opening on the stage, they have gained a lot of attention. # Kym first appeared on the show and responded that she was 19 years older than her boyfriend #, # Kym responded to the called female oil king #, # Moka Fang responded to taking economy class #, # Gina used kiss to reduce Lang Lang’s fever # and other related videos have a good spread.

Variety derivative also has new content dynamics. On the one hand, it is a continuation. The "Detective 9 Detective Concert" broadcast in two sessions still continues the payment mode. The first broadcast volume has reached 6000w+, which shows the strong purchasing power of fans. On the other hand, it broke the boundary of the original program content. Tencent video’s characteristic workplace variety "Exciting offer" launched the group comprehensive "offer to Adjust the Bureau". One of the producers of the program was the investigation team (formerly the Ming investigation team), which opened a new door to workplace reasoning with classic werewolf killing. The data of the weekly list of Guduo Variety Heat Index shows that the "offer Best Tune" has climbed to the second place on the list in less than a week and has become a new representative of derivative programs.

New variety shows continue to be updated, such as the documentary program "Ten Thousand Years of Life" launched by Mango TV, the special program "Young People See the World" of Hunan NPC and CPPCC in 2024, and the listening talk show "Listen to You Say So" hosted by Li Jing, which focuses on the track of documentary, NPC and CPPCC, interviews and other content, focusing on steady progress.

On the whole, the variety track in the opening year of 2024 is still in the initial layout stage, which is mainly based on the recognized comprehensive N-generation and a small number of new programs, and it has not brought too many innovations and surprises in the program types and modes. Occasionally, some program fragments can set off a small-scale discussion on social platforms, but the whole has not brought a clear signal to the variety market in the new year.

However, it is worth mentioning that Tencent Video released the list of comedy variety shows in 2024, and many different comedy variety shows such as Comedy Conference, Wonderful Night, Easy Comedy Festival, HAHA MAKER Department Store, Talk Show and Friends of TA will also meet the audience. Presumably, this year’s comedy track will be dazzling and powerful.

Indeed, based on the new year, the major platforms have been gaining momentum for a long time in the layout of the variety and drama sections. Then February will usher in the longest Spring Festival holiday in history. What new points will appear in the drama market? It is worth looking forward to!

Former Iowa Congressman wrote to Shanghai Daily: Trade disputes make too many American farmers unhappy.

  "Too many American farmers are unhappy, and as the dispute persists, more people are confused about the future." A former congressman from Iowa wrote this at the beginning of his letter to the China media "Shanghai Daily".

  On June 17th, Shanghai Daily published an in-depth English report by Xinhua News Agency, entitled "Floods and US-China Trade Disputes Bring Disastrous Disastrous by Historical Floods". The article objectively reflects natural disasters and trade disputes, especially the disasters brought by the latter to American farmers. The article mentioned that since the end of March this year, the continuous floods in the midwest of the United States have made local farmers complain. Blake Hurst, president of Missouri Farmers’ Association, said that such a large-scale serious flood that swept across the central and western regions had never happened in his memory of farming for more than 40 years. In addition to natural disasters, the trade dispute with China provoked by the US government has further aggravated the plight of farmers in the Midwest of the United States. Trade disputes have caused a sharp decline in US soybean exports to China, lower soybean prices, greatly reduced farmers’ income, and many farmers are facing economic difficulties. Although the U.S. government launched a subsidy assistance program of $12 billion last year and $16 billion this year, the affected farmers told reporters that they wanted a stable market more than subsidies.

  Shortly after the article was published, Shanghai Daily received a letter from Greg Cusack, a former representative of Iowa. Kusak said in his letter: "Too many American farmers are unhappy, and as the dispute persists, more people are confused about the future."

  Kusak pointed out that because "Republicans are used to making a fuss about a single political issue, throwing salt at the wound and the rural areas where the Democratic Party depends on are dying day by day", American farmers feel quite helpless and have no choice. The Democratic Party is far from finding a package solution for agriculture or rural areas, which makes the situation even worse.

  Kusak also said in his letter that Xinhua News Agency and other related articles published by Shanghai Daily reported on American farmers and other issues extensively and were in line with the facts. In contrast, some American media reports on domestic and foreign news in the United States are very lacking, which is far from meeting the needs of even readers with general knowledge background.

  In his letter, he also described various manifestations of the increasingly divided American society, and pointed out: "I think the Shanghai Daily is very extensive in reporting these topics of concern, and I hope your newspaper will continue to report these problems in the United States, despite the current trade friction between the United States and China. These problems show that American society is in a dilemma. They include: high student debt (which is also high after graduation), stagnant wages, widening wealth gap and rural difficulties. "

  This is not the first time that Kusak has written to Shanghai Daily. Wang Yong, deputy editor-in-chief of Shanghai Daily, told The Paper (www.thepaper.cn) that after reading the in-depth comments on Shanghai’s construction of beautiful countryside published by Shanghai Daily, Kusak wrote a special letter praising China’s great efforts to revitalize the countryside under the leadership of the Supreme Leader General Secretary, and pointed out that the support of the two parties in the United States to the countryside was lip service, which led to the decline of American agriculture and rural life. His letter was also published in the commentary section of Shanghai Daily.

  Kusak was a representative of Iowa, and one of his main tasks was to revitalize rural areas and agriculture in the United States.

  Wang Yong told The Paper that Kusak has repeatedly supported China’s just position on major issues, such as the South China Sea issue and Internet management, and he has written to actively support China’s position. He also studied the history and traditional culture of China at his own expense. Two years ago, he also facilitated a senior commentator of the Des Moines Chronicle in Iowa to come to Shanghai to interview the Shanghai Daily, affirming China’s news reporting concept. After returning to the United States, the reporter from Des Moines Chronicle wrote an in-depth report on the media, hoping that the United States would stop being biased against the China media.

  "Kusak has been writing to tell us that the American press is not only the Wall Street press, but also an agricultural state like Iowa. The press is friendly to China, and the report is objective and rational. He hopes that Iowa will make greater contributions to Sino-US friendly cooperation. " Wang Yong said.

  The report published in Shanghai Daily and the letter from Greg Cusack are as follows.

  Midwest farmers devastated by historic floods, ongoing US-China trade tensions

  (Shanghai Daily, June 17))

  About 10 days after the latest round of rainfall, half of Tom Waters’ farmland is still under water. “Some of it’ s flooded from the river. Some of it’ s flooded from seep water. Some of it just rain water that has nowhere else to go because it won’ t drain,” said the seventh-generation farmer.

  Waters and his family farm about 3,500 acres (1,416 hectares) of land in Orrick, Missouri, a small town east of Kansas City. Among his nearly 1, 700-acre rain-soaked fields, 900 acres were swallowed by the surging Missouri River when a levee broke on June 1 and are still up to 4.5 meters below water.

  He had planted a few acres of corn, with the rest intended for soybeans, but “it’ s just gone now,” Waters told Xinhua, estimating the loss to be “several hundred thousand dollars.”

  When the flood hit, Waters had to move out some 60,000 bushels (1,633 tons) of soybeans in storage, and sold them at “a pretty low price, ” about US$3 a bushel off the normal price prior to the US-China trade tensions. “That’ s a lot of dollars difference for us,” he said.

  “This has just been rain after rain. Before it even dries out it rains again. It’ s been week after week after week like that,” said Waters, who has been farming for over 40 years in this area, adding that the persistent wet weather is a “very rare event.”

  Noting that reservoirs up in Montana, North Dakota and South Dakota still have too much water to dump, the seasoned farmer worried that “the river is going to be high all the rest of spring and through summer, so chances are we won’ t get any of this (flooded land) planted this year.”

  Blake Hurst, president of the Missouri Farm Bureau, also a corn and soybean farmer in Tarkio, northwest Missouri, told Xinhua that he saw similarly catastrophic floods in this area in 1993, but such a widespread severe flooding throughout the Midwest is the worst he can remember. “The last 12 months, in the center part of the United States, have been the wettest 12 months on record,” said Hurst, who has about 500 acres of land under water, noting that the relentless rain since late March has contributed to significant planting delays.

  In the biggest corn-producing states, farmers had planted 83 percent of corn acreage by June 9, compared with a five-year average of 99 percent, according to the latest data from the US Department of Agriculture (USDA).

  Hurst, who also has 40-plus years of farming experience, said corn should ideally be planted by the first week of May, and a one-month delay could cut the normal yield by roughly 20 percent, as there might not be enough time for it to mature before the frost hits the ground. The seemingly relentless rain in the Midwest has left farmers dro wning in frustration. On top of that, many growers have been bearing the brunt of the US-initiated trade dispute with China, struggling with financial hardship and facing an uncertain future.

  “We’ ve seen a big cut in our (soybean) exports to China because of the trade tension, and that’ s caused prices to drop,” Hurst said, adding that several months of trade frictions have “made a big difference” to farmers’ income.

  Noting that the United States has had five years of above average crop yields, Hurst said that already led to an oversupply. A decline in exports to China, caused by the trade tensions and compounded by the African swine fever outbreak, has worsened the situation, he said.

  ‘ Not a dependable supplier’

  “It’ s just a combination of all of them that has really made farming kind of difficult this year,” Hurst said. “It just keeps on and coming.”

  For Waters, a combination of circumstances has made planning nearly impossible. “I think this has been the hardest year to make decisions for me since I’ ve been farming,” he said.

  Waters said it has been stressful to wait for a resolution to the trade dispute. “You keep thinking, well maybe tomorrow, maybe tomorrow, then you hear a little bit of good news and maybe the price bumps up a little bit and then that blows up and it goes back down. So it’ s just been difficult,” he said. Hurst, who farms 6,000 acres of land with his family, usually plants corns on half of the acreage and soybeans on the other half. Earlier this year, he had planned to plant 5 to 10 percent more corn because of the trade dispute and lower demand for soybeans. The unusual wet spring, however, makes that goal unfeasible.

  “Now, anybody that’ s shifting will shift to soybean simply because it’ s too late for corn,” Hurst said, adding that if soybeans don’ t get planted by this week, farmers will start to lose yield as well.

  However, the USDA data shows that growers in the major soybean-producing states had only planted 60 percent of acreage by June 9, far below a five-year average of 88 percent. Speaking of the newly approved disaster relief bill and the new round of trade aid package, Hurst urged the administration to announce detailed rules of these programs quickly so that farmers can better plan.

  Noting that it took Congress months to pass the disaster relief bill, Waters said he doesn’ t expect to receive any money until weeks later. Still, he prefers a stable market rather than a trade aid package. “The question has to be, are we losing these markets permanently?” Hurst said, noting that trade tensions in some ways make the United States “not a dependable supplier” for soybeans.

  “Obviously we’ re going to put tariffs on you. We’ re going to announce tariffs in a tweet. So they can happen at any time. So if I’ m a grain buyer anywhere in the world, I’ m looking for a supplier I can trust, and we’ re no longer that supplier,” he said. “We’ ll be paying for this for years.”

  Media role in informing US farmers

  Letter from Gray Kusak, published in Shanghai Daily on June 21st.

  I wrote this after reading “Midwest farmers devastated by historic floods, ongoing US-China trade tensions” in the Shanghai Daily (June 17). One heck of a lot of farmers in America are not happy, and an even greater number are very worried about how this will all play out, especially the longer the stand-off continues.

  The age of the average farmer continues to increase, the prices they receive for their crops are stagnant, the costs of the inputs nonetheless are increasing, and corporate mono-crop “farming” is harming land, air, and water (the dead zone in the Gulf of Mexico is larger than ever).

  So, are they just stupid, misinformed, or what?

  I think the problem is really the vast division in our country caused by the culture wars — the real, but deliberately exaggerated, tensions between generations, the urban-rural divide, the skillful way the Republicans keep single-issue politics picked raw, and the marked decline in rural districts that are Democratic leaning. In a sense, many farmers thus believe that they have nowhere else to go.

  The Democratic candidates have yet to produce, at least to my knowledge, anything that could remotely be described as a farm or rural program package, making the situation even more dire.

  I think the wide range of concerns covered by the Shanghai Daily is truly remarkable, and I hope that despite current tensions you will continue to cover matters in the US, including the many indicators that we are a society in deep trouble: such as levels of student debt after graduation, still largely stagnant wages, the ongoing widening disparity of wealth and the genuine plight of rural America. In contrast, newspapers in the US are not doing so well. The Oregonian, the newspaper published in Portland and its metro area of a few million, is nothing like what it was in the recent past.

  They now deliver paper editions to subscribers only four days a week, expecting that on other days people will use their digital apps to access them. And their national, let alone international, coverage is insufficient to provide the information even half-informed citizens need.

  The author is a retired US statesman. He now lives in Oregon.

  The Chinese version of the report published in Shanghai Daily and the article written by Greg Cusack are as follows:

  Close-up: The spring sowing season with floods and trade disputes has brought too many difficulties to American farmers.

  (Xinhua News Agency, June 14, 2019)

  Xinhua News Agency, Auric, USA, June 13th (Reporter Xiong Maoling, Hu Yousong) In Auric, a small town in central Missouri, USA, Tom Waters, who was over 60 years old, pointed to a muddy water area and told Xinhua News Agency that there were nearly 1,000 acres (1 acre is about 0.4 hectares) of his farmland here, but it was a pity that it was flooded after the Missouri River burst its banks earlier this month.

  The Waters family has been farming for seven generations. At present, they have more than 3,500 acres of farmland, mainly growing soybeans and corn, but half of the farmland has been affected. He said that due to the large amount of water storage in reservoirs in Montana and North Dakota in the upper reaches, it is necessary to open floodgates and flood discharge, and it is estimated that his flooded farmland will not be seen again until the end of the summer.

  "(The flooded farmland) may not be able to grow anything this year." Waters said helplessly that he expected that the flood would cost him hundreds of thousands of dollars.

  Since the end of March this year, the continuous floods in the midwest of the United States have made farmers like Waters complain, and the sowing process has been delayed again and again. According to data from the US Department of Agriculture, as of last week, about 83% of corn fields in the United States have been sown, which lags behind the average of 99% in the same period of the past five years; The soybean planting completion rate is 60%, which is also lower than the average level of 88% in the same period of the past five years.

  Blake Hurst, president of Missouri Farmers’ Association, told reporters that such a large-scale serious flood that swept across the central and western regions had never happened in his memory of farming for more than 40 years. He said that even if the flood recedes, the flooded farmland will have to wait for time for the soil to recover, which means that some farmland will miss the whole sowing season.

  Hearst said that the best sowing date of corn has passed one month. If we start planting corn now, I am afraid we can only achieve 80% harvest this year. The sowing window of soybeans is also narrowing. If the sowing cannot be completed next week, the soybean output will be affected this year.

  Not only is it a natural disaster, but the trade dispute with China provoked by the US government has aggravated the plight of farmers in the Midwest of the United States. Hearst said that the trade dispute caused a sharp drop in US soybean exports to China, lower soybean prices, greatly reduced farmers’ income, and many farmers faced economic difficulties.

  Hearst said that in the past five years, the rare continuous high yield of soybeans and other crops in the United States has already caused an oversupply, while the economic and trade friction has reduced the demand for American soybeans in China, a big market, and the oversupply of American soybeans is even more serious. "These factors are superimposed together, making it difficult for farmers this year."

  Waters originally hoarded 60,000 bushels of soybeans (1 bushel of soybeans weighs about 27.2 kilograms) for sale when the price picked up. However, due to the flood this spring, he had to transfer his inventory in time and have a sale at a low price. Compared with the soybean price before the Sino-US economic and trade friction, he lost about $180,000.

  Compared with many farmers, Waters is lucky. It is understood that in Nebraska, Iowa, Missouri and other States, floods not only flooded fields, but also swept some barns, and farmers could only watch helplessly as the food that was too late to rush was wiped out.

  Waters admits that this year is the most difficult year for him to make a decision since he was a farmer, and he has spent many "sleepless nights". He has been expecting the United States and China to reach an agreement as soon as possible to resolve the trade dispute, but the waiting process makes him anxious.

  "I’ve been thinking about it, maybe tomorrow (an agreement will be reached), and then I heard a little good news, and then the price of soybeans went up a little, and then the expectations failed and the price fell again. This is not easy for all farmers." He said.

  For Hurst, who owns 6,000 acres of farmland, the planting season this spring is also very difficult. Hearst’s farmland is located in Tacchio, a small town in the northwest corner of Missouri. In previous years, he usually planted half soybeans and half corn. Hearst originally planned to plant hundreds of acres of corn this year because of the reduced demand for soybeans caused by economic and trade frictions. However, the continuous rainfall has repeatedly delayed his corn sowing plan and missed the best sowing date. Now, if he replants soybeans, he will face the uncertainty of market demand.

  In order to make up for the losses caused by economic and trade frictions to farmers, the US government introduced an agricultural subsidy plan of about $12 billion last year to provide certain subsidies to farmers of crops such as soybeans. But Waters said that the soybeans he produced last year were only partially subsidized.

  In late May this year, the US Department of Agriculture announced that it would provide farmers with up to $16 billion in aid to compensate them for the losses they suffered in economic and trade frictions. But Waters doesn’t expect to get money soon. He wants a stable market more than government subsidies.

  Hearst also expressed concern about the market prospects. He said that the U.S. government’s actions of arbitrarily imposing tariffs and provoking trade disputes will make the United States lose its status as a "reliable supplier" and cause long-term negative effects. "We will pay the price for this for many years." (Participating in reporters: Gao Pan, Liu Jie)

  Letter from Gray Kusak.(Chinese translation)

  After reading the article published in Shanghai Daily on June 17th ("Floods and trade disputes bring disasters to farmers in the Midwest of the United States"), I started writing to your newspaper. Too many American farmers are unhappy, and as the dispute persists, more people are confused about the future.

  The average age of American farmers is getting bigger and bigger, the production cost is getting higher and higher, but the price of agricultural products is stagnant, and the company’s single-variety planting behavior has brought harm to land, air and water (the "dead zone" in the Gulf of Mexico is increasing day by day. )

  Is all this because American farmers are stupid? Or is it because their information is wrong, or other reasons?

  In my opinion, the real root of the problem lies in the social gap caused by the cultural war in our country – Generational conflicts (real but deliberately exaggerated), urban-rural division, Republicans’ habit of making a fuss about a single political issue, throwing salt into the wound, and the rural areas on which the Democratic Party depends are dying. It can be said that many farmers in the United States feel quite helpless and feel that there is no way to go. The Democratic Party is far from finding a package solution for agriculture or rural areas, which makes the situation even worse.

  I think Shanghai Daily has a wide coverage of these topics of concern. I hope your newspaper will continue to report these problems in the United States, despite the current trade friction between the United States and China. These problems show that American society is in a dilemma. They include: the debt of students remains high (even after graduation), the wages are mostly stagnant, the wealth gap is widening, and the countryside is in trouble.

  Contrary to your newspaper, American newspapers are not doing well. For example, The Oregonian, published in Oregon and surrounding areas with millions of people, is not as good as it used to be. The quality edition of the newspaper is only published four days a week, and the rest of the time readers are expected to read it through electronic applications. (In the case of such a shrinking newspaper industry), not to mention international news, even domestic news in the United States is poorly reported, which is far from meeting the needs of readers with only general knowledge background.

Guo Tong, Chairman of CCTV Network and General Manager of Central Video Company: Promote the development of micro-short dramas, and the new media platform of Headquarters "Play the Future"

  On December 21st, the "Fine Micro-Short Drama Cooperation Seminar" was held in Hangzhou. At the meeting, it was announced that more than 20 media organizations will create excellent mini-dramas in the coming year around the three major themes of "Xiangyang, Goodness and Beauty" and the six directions of "Dream, Youth, Warmth, Revitalization, National Style and Imagination". The State Administration of Radio and Television, China Network Audiovisual Association and nearly 100 media representatives attended the seminar.

  Guo Tong, Party Secretary and Chairman of CCTV International Network Co., Ltd. and General Manager of Central Video Media Development Co., Ltd., attended the seminar and shared his speech.

  In his speech, he said that the reception desk has always maintained close strategic cooperation with Hangzhou, Zhejiang. At the beginning of this month, China Short Video Conference, a large-scale integrated media program originally produced by CCTV, Zhejiang Provincial Party Committee Propaganda Department and Hangzhou Municipal People’s Government, held an award ceremony in Hangzhou.

  As the first large-scale project after the National (Hangzhou) Short Video Base was jointly established by the Headquarters and Zhejiang, the China Short Video Conference ended successfully with 1 billion+video broadcasts and 1.4 billion topic readings. During the 19th Asian Games in Hangzhou, the creators went to Hangzhou to produce 32 short quality video works, which showed many highlights in Hangzhou, and let the audience and netizens see warm stories of China in these works.

  "China Short Video Conference" brings together the top creators of the whole network in eight tracks, including plays, food, sports and fashion. It is worth mentioning that the drama track shows many excellent creators. Their short and exquisite works can not only meet the viewing needs of short video audiences, but also be full of creativity, appeal and positive energy.

  The creator who won the championship in the drama track "This is the story of TA", with 20 million fans on the whole network. In the proposition creation stage of the program, "This is the story of TA", with the title of "Xiajiang Xinyan", tells the story of young people’s struggle to start a business in Xiajiang Village, Hangzhou with a 4-minute short story. The release of this short film in Tik Tok was jointly released by Central Video Account and Creator Account, and achieved good communication effect. Among them, there is such a highly praised comment: "The stories of these two people explain what is positive energy, what is romance, and what is life, but also poetry and distance. The listener was moved and the listener shed tears. " This is the "boutique" recognized by the audience.

  Guo Tong believes that these vivid practices and explorations have made everyone see the example of short video quality, and also convinced everyone that there is much to be done in fine micro-short dramas.

  As an important platform for new media in the main station, CCTV and CCTV are also paying attention to the dynamics and development in the field of micro-short dramas. Guo Tong took the precious opportunity of the "Cooperation Seminar on Fine Micro-short Drama" to share some personal views and explore the road of fine development of micro-short drama.The following are the main contents of the speech:

  01. Focus on "excellent products" and lead the future.

  This year’s national conference on propaganda, ideological and cultural work formally put forward the cultural thought of the supreme leader, which is a milestone in the history of the development of the party’s propaganda, ideological and cultural undertakings and provides a fundamental basis for us to do a good job in cultural work in the new era. We firmly believe that under the guidance of the supreme leader’s cultural thought, the emerging short drama industry will keep up with the pulse of the times and continue to glow with vitality.

  (A) industry standards are improving day by day.

  In the past two years, the categories of micro-short dramas have been increasingly enriched, users have gradually cultivated, and the market scale has steadily increased. Micro-short dramas have rapidly grown from a "new force" in the field of network audio-visual to a "new force" that has attracted worldwide attention. We can see that micro-short plays have innate characteristics such as fragmentation, speediness and low cost, which not only brings about the rapid development of the micro-short play industry, but also brings some problems such as mixed content and deviation in value guidance.

  From the perspective of audience feedback, there are some problems in short drama works, such as homogenization of content, exaggeration of interpretation, low production standard, abuse of plot and lack of innovation, and the audience’s demand for innovation and change is increasing day by day.

  Judging from the development law of the network audio-visual content ecology, whether it is short videos, online movies or online dramas, they have all experienced the early period of "barbaric growth" and have all been guided correctly and reasonably before they finally achieve a double harvest of social and economic benefits. Recently, the State Administration of Radio, Film and Television (SARFT) issued a timely notice on the content review of short plays. The review of short plays has the same standard and scale as the traditional long-term online film and television dramas, which has set a direction and escorted the rapid development of short plays.

  (B) Fine miniseries are promising.

  We can see that with the joint efforts of the competent authorities, platforms, creators and media, the short drama industry has achieved rapid iteration and aesthetic upgrading, and the quantity and quality of fine micro-short dramas have steadily improved. Escape from the British Museum, a popular explosion in the whole network, Grandma Please, and The Chaser, a spy war theme, have achieved breakthroughs in many dimensions, such as creative transformation, commercial customization, content derivation, and integrated communication, and also brought inspiration to the creation of fine short plays.

  (C) the mainstream media set a benchmark

  "Carrying forward the main theme and spreading positive energy" is the mission responsibility of mainstream media. Guided by the integrated communication of "thought+art+technology" of the main station, we will make full use of the new carrier of micro-short drama, and actively create and gather high-quality short dramas with "times, people and leading" with the attitude of courageously taking the lead and doing our best to set a model benchmark for the industry.

  Pay attention to "seeing the big from the small", show the "big times" with "short stories", show the "big themes" with "small incisions", record the real life of contemporary China, and depict the spirit of striving for progress in the new era.

  Pay attention to "cultural inheritance", spread Chinese excellent traditional culture, and make unremitting efforts to continue the Chinese context and promote the creative transformation and innovative development of Chinese excellent traditional culture.

  Pay attention to "integrity and innovation", constantly optimize and innovate the content creation and presentation form, and continue to help tell the story of China and spread the voice of China.

  02. Create "excellent products" and March towards the future.

  CCTV and CCTV strive to lay out the field of high-quality micro-short dramas in depth and comprehensively. We plan to launch large-scale projects of high-quality micro-short dramas such as China Micro-short Drama Conference and China Micro-short Drama Festival, so as to blow the "assembly number" of high-quality micro-short dramas on the whole network with the appeal of the new media of the main station, and boost the development of high-quality micro-short dramas. Around this series of format projects, we will make positive and beneficial attempts in the field of micro-short plays.

  (A) to create a "wind vane"

  We hope to join hands with all major platforms to create a new format of micro-short drama.

  We plan to set up the first national authoritative mini-short drama judging system, and gather nearly 100 experts, scholars and senior practitioners from content, technology, communication, market and other related fields to explore the industry standards of mini-short drama with practical actions.

  We plan to combine data and index media inside and outside Taiwan, such as "Elephant Dance Index", to create a "wind vane" for micro-short drama creation.

  (B) Build an "incubator"

  We hope to play the role of ecological "incubator" and explore industrial construction and ecological development.

  We welcome and invite all forces to join us, and jointly create a series of measures, such as the support plan for fine micro-short dramas, the excellent creator plan, and the local industry incentive plan, to give wings to creators with good content and strength, to continue to support the blooming of fine micro-short dramas, and to boost the high-quality development of the micro-short drama industry.

  (3) The combination of length and length is wonderful.

  We hope to gather the strength of all parties, actively explore new modes of cooperation, give full play to the advantages of the communication matrix of the main station, and integrate the multi-dimensional communication chain of the large and small screens of the main station, so as to build a bridge leading to thousands of households for the fine micro-short dramas, so that the fine content can stand, stay and spread, and help the micro-short drama ecology to achieve the unity of economic and social benefits.

  03. Explore "mini-drama+"and embrace the future.

  I also have some thoughts about the future of fine miniseries, hoping to "play the future" with all my colleagues.

  (A) explore "micro-short drama+central and local linkage" to empower urban cultural tourism.

  In recent years, the new media of Headquarters has accumulated many effective cases in the linkage between central and local governments, breaking through the traditional urban propaganda mode. From the standpoint of central media, we can see the importance of urban development and shape the soul of urban brand. From high-quality short videos, in-depth live broadcasts, tourism and cultural festivals to large-scale parties and seasonal programs, it provides a unique contact for the audience to understand the place. The China Short Video Conference is one of the excellent demonstration cases of the "central-local linkage" of the main station.

  We can also see that many cities have begun to try to develop the micro-short drama ecology in local areas. For example, many places in Hangzhou have developed film and television bases for micro-short plays, and many supporting policies have been introduced that are conducive to the production of micro-short plays.

  In the future, CCTV and CCTV will continue to innovate the cooperation mode between the central and local governments, flexibly use the creative means of micro-short plays, and closely integrate with the cultural tourism resources of various cities. Representative characteristic foods, folk festivals, history and culture, and people’s lives in the city can be the themes of mini-dramas.

  (B) explore "mini-drama +AI" and upgrade the mode of production.

  The development of technology has brought subversive changes to content production, and it is also continuing to empower artistic creation. Nowadays, the wide application of AI technology will make the production of miniseries more professional, industrialized and efficient. Making better use of cutting-edge technologies such as AI will hopefully further open up the imagination space of miniseries. Scene building, intelligent interaction and other functions are gradually improving the personalized needs of various creations.

  (C) explore "micro-short drama+overseas communication" to realize the "going out" of culture.

  Since the second half of this year, the pioneer fleet of China miniseries has sailed to the other side of the ocean with a swift and violent trend, and the miniseries’ performance in going out to sea is outstanding. We are also paying close attention to this trend. Although the quality of works at sea is mixed at present, the trend of high-quality products will gradually blow from China to the world. Based on a strong overseas market and a wide overseas audience, it is also the responsibility and mission of China as a media platform to create a good opportunity for China culture to spread abroad with fine and high-quality content with the help of micro-short plays.

  As the important platforms of new media in the main station, CCTV and CCTV encourage the exploration of new cooperation paradigms, and will establish and optimize cooperation mechanisms, and advocate the creation of a platform for the development of micro-short dramas with joint research, co-construction, sharing and win-win. We look forward to working with you to "lead the future", "March towards the future" and "embrace the future" — — "Play the future".

China has not and will not use the exchange rate as a tool to deal with trade disputes.

  The US Treasury Department issued a statement in the early morning of August 6th, Beijing time, and decided to list China as a "currency manipulator". In this regard, experts believe that China adheres to the exchange rate system determined by the market, and there is no problem of "exchange rate manipulation". China does not engage in competitive devaluation, does not use the exchange rate for competitive purposes, and does not use the exchange rate as a tool to deal with external disturbances such as trade disputes. 

  "The depreciation of the RMB exchange rate on August 5 is largely due to the increase in tariffs imposed by the United States on China, the increase in pessimism about China’s balance of payments and the RMB in the market." Yu Yongding, a member of the China Academy of Social Sciences, said that it can be said that it is caused by the American practice and has nothing to do with the People’s Bank of China. 

  At present, whether the RMB exchange rate rises or falls, it is determined by the market, not the result of human manipulation. "In terms of mechanism, the RMB exchange rate is determined by market supply and demand, and there is no ‘ Exchange rate manipulation ’ The problem. " Wen Bin, chief researcher of China Minsheng Bank, said that at present, China is implementing a managed floating exchange rate system based on market supply and demand, with reference to a basket of currencies. Since China implemented the reform of RMB exchange rate formation mechanism in July, 2005, it has continuously improved the quotation mechanism of the middle price and expanded the floating range of RMB against the US dollar on the basis of the middle price, from 3‰ Expanding to the current 2% can fully reflect the relationship between market supply and demand, and the degree of marketization of RMB exchange rate has been significantly improved. 

  Especially since the "8.11" exchange rate reform in 2015, the two-way fluctuation of RMB has become more obvious, the exchange rate flexibility has been significantly enhanced, and the degree of marketization has been greatly improved. Taking the trend of RMB in 2018 as an example, since the middle and late April of 2018, the RMB exchange rate has started a downward trend, and by the end of June, it has dropped all the previous increases. In November, after the RMB exchange rate hovered around the 6.9 mark, it ushered in a strong rebound in December and finally "recovered lost ground". In this process, whether the RMB exchange rate appreciates or depreciates, it is a reflection of the expected changes in the market, rather than artificial manipulation. 

  The recent "breaking 7" of RMB exchange rate is also a reflection of China’s adherence to the market-determined exchange rate system. Wen Bin said that recently, due to the global economic slowdown, interest rate cuts by many central banks, increased trade frictions and other factors, the international financial market has fluctuated violently, and the RMB exchange rate has also fluctuated under the influence of market and sentiment, which is precisely a reflection of the marketization of the RMB exchange rate. 

  Some people think that the devaluation of the RMB at this time is China’s response to trade disputes. 

  "The depreciation of the renminbi has no definite benefits for China." Yu Yongding said that RMB depreciation has both advantages and disadvantages, and the impact is uncontrollable. There are too many uncertain factors for China to devalue. For example, after devaluation, it may stimulate capital outflow, which may aggravate the devaluation. In the long run, this is not conducive to maintaining a general balance in China’s foreign trade, and devaluation will also make the burden on the whole country heavier. 

  From this point of view, China’s initiative to guide devaluation has too many side effects, which may do more harm than good. Therefore, we will not intentionally devalue the RMB exchange rate. 

  Yu Yongding emphasized that "China does not engage in competitive devaluation, does not use the exchange rate for competitive purposes, and does not use the exchange rate as a tool to deal with external disturbances such as trade disputes". These three policies are China’s policies, and no country will formulate and implement policies that are uncertain about its own benefits. Therefore, it is not China’s choice to deliberately guide devaluation.

  "There are many ways to deal with economic and trade frictions, and there are too many negative spillover effects of using the exchange rate, so it is unnecessary for China to take this measure." Li Yong, deputy director of the Expert Committee of China International Trade Association, said that as a responsible big country, China should be responsible not only for itself, but also for its major trading partners. Not engaging in competitive devaluation is conducive to China’s cooperation with its major trading partners, which is in the interest of China. 

  China has not used and will not use the exchange rate as a tool to deal with external shocks. "Even after the outbreak of the Asian financial crisis, China did not choose to devalue to deal with the impact. At a time when the internal and external shocks are still far from the crisis, active depreciation will not be an option for China. " Li Yong stressed. 

  Li Yong believes that the United States accuses China of manipulating the exchange rate at this time. This unilateral act of the United States undermines the global multilateral consensus on the exchange rate issue, which will seriously hinder international trade and global economic recovery, and will be beneficial to both people and themselves, and will eventually reap the consequences.

Next, look at the camera part. Although the iPhone 14 Pro/Pro Max series is still a three-camera scheme with super wide angle+wide angle+telephoto, and equipped with a LiDAR lens, the main camera is upgraded to a brand-new 48-megapixel sensor for the first time, with a unit pixel area of 1.22μ M, supporting the four-pixel integration technology, and the unit pixel area can reach 2.44μ M, the lens aperture is f/1.78, the lens focal length is 24mm, and it is equipped with the second generation sensor displacement anti-shake technology. However, on the ultra-wide-angle and telephoto lenses, they still maintain 12 million pixels, the equivalent focal length of telephoto lens is 77mm, and the equivalent focal length of ultra-wide-angle lens is 13 mm.

In terms of camera module size, the camera module size of iPhone 14 Pro is slightly larger than that of iPhone 13 Pro.

Although the "Microcomputer Branch" does not indicate the suppliers of the lens module, image sensor and laser radar module of the iPhone 14 Pro series, according to the previous data, the rear lens module of the Pro series should be mainly supplied by Dali Light, and the image sensor is mainly supplied by Sony. The rear lidar module is mainly supplied by Sony. As for the front Face ID module, the Face ID of iPhone 13 series was previously supplied by Foxconn and LG Innotek, but the Face ID of 14 Pro series has been improved, so it is uncertain whether it will still be supplied by these two companies.

There is a dustproof and waterproof apron around the inside of the rear flash of iPhone 14 Pro, which is quite different from the previous generation. After violent disassembly, it can be seen that the rear flash of iPhone 14 Pro has changed from two bulbs in the previous generation to a big bulb, but Apple has divided it into nine parts, which can adaptively control the flash intensity, brightness and uniformity. Both have improved.

Summary:

Judging from the above disassembly report and the existing public information,Although the hardware configuration of the iPhone 14/14 Pro has not been greatly upgraded as that of the Pro series, its internal structure has been redesigned, and the "sandwich" design has greatly improved the maintainability.

Therefore,IFixit gave a high score of 7 (out of 10) for the repairability score of iPhone 14, which is also the highest score since iPhone 7. IFixit even said: "This is a big event, and Apple should make a major statement that the iPhone 14 has been redesigned from the inside out to make it easier to maintain."

Sam Goldheart of iFixit thinks: "In this era, product launch should not just brag about some small new features. Why doesn’t Cook brag about repairability? We didn’t know this would happen because Apple didn’t mention it at all. But they should do so. "

In addition, the two-way satellite communication function introduced by iPhone 14 series is also a focus of attention. The reason why the iPhone 14 series can support two-way satellite communication is mainly due to the upgrade of Qualcomm Snapdragon X65 baseband chip and Apple’s self-developed RF antenna.

According to previous data, Qualcomm Snapdragon X65 baseband chip can not only support the downlink rate up to 10Gbps, but also cover all major 5G bands including millimeter wave and Sub-6GHz band and their combinations. It is confirmed that the satellite communication of iPhone 14 series is supported by Qualcomm Snapdragon X65. The baseband chip has added a new 2.4 GHz n53 band function to support the satellite of Globalstar, a satellite communication company cooperated by Apple.

ICJay Monroe, executive chairman of Globalstar, boasted at the press conference earlier this year: "We appreciate the close relationship with Qualcomm since the company was founded, and thank their team for their hard work in helping us realize the promise of Band n53." Globalstar previously announced that it agreed to use 85% of its current and future satellite network capacity to support the two-way satellite communication function of iPhone.

In addition, the addition of two-way satellite communication function, coupled with many existing communication functions such as 5G, WiFi, Bluetooth and GPS, not only greatly increases the number of antennas, but also brings greater challenges to antenna design. During the disassembly, we also saw some new designs of Apple on the antenna.

Disassembly also shows that although the iPhone 14 Pro series still uses 6GB of memory, it uses the latest LPDDR5 technology, while the previous generation iPhone 13 series is LPDDR4X.

Detailed disassembly of iPhone 14 and iPhone 14 Pro: Chinese mainland suppliers make great strides!

Earlier, Apple had indicated that it would not consider using Changjiang storage flash memory in iphones sold in markets outside China, so we didn’t see the version using Changjiang storage flash memory in the disassembly of the US version of iFixit iPhone 14 series.

However, the three National Bank versions of the iPhone 14 series dismantled by Calculus have not found any flash memory with Yangtze River storage. But,According to the disassembly video of the National Bank version of iPhone 14 Pro Max released by a domestic blogger, the disassembled version uses flash memory supplied by Changjiang Storage.

Judging from the changes in the supply chain of Apple’s iPhone in recent years, the proportion of Chinese mainland suppliers in the Bank of China version of iPhone is growing continuously.

This may also be a measure taken by Apple to reduce the supply chain risks caused by the "US-China science and technology war" and "geopolitical issues".

KFC sells its China business in a low-key way, while McDonald’s sells it in a high-key way.

  Unlike McDonald’s high-profile packaging of China stores for sale, KFC, another iconic American fast food chain giant, unexpectedly sold its China business in a low-key manner. The night before yesterday, Yum! Brands, the parent companies of KFC and Pizza Hut and listed on the new york Stock Exchange, announced that Yum! China would be separated from Yum! Brands and listed on the NYSE as an independent company. At the same time, after the spin-off, Yum! China will receive a total investment of US$ 460 million from Chunhua Capital and Ant Financial. This means that Yum! Brands has sold part of its operations in KFC and Pizza Hut in China to two purchasers from China.

  Yum!’ s business in China has fallen into a trough?

  In fact, Yum! Brands has already paved the way for China business. Last October, it announced that it planned to split Yum! Brands and Yum! China, and this transaction was carried out on the basis of that split at that time.

  KFC is the first American fast food chain brand to enter the mainland market in China. In 1987, it opened its first store in Qianmen, then the most prosperous business district in Beijing. At that time, it was fashionable for both Beijingers and foreign tourists to queue up for a fried chicken or a hamburger at KFC. And KFC’s rule of "throw away the food after it has been sold for 90 minutes" brought from the United States has also attracted the attention of consumers in China. It is likely that KFC’s great success in exploring the China market attracted McDonald’s. Subsequently, McDonald’s also entered the mainland market of China in 1990. For a long time after that, these two brands were the iconic brands of American fast food culture in China.

  In 2015, China accounted for half of the global business of Yum! Brands. However, this data can’t hide its downward trend in the China market. Since the incident that Shanghai Fuxi reprocessed expired meat raw materials and changed the shelf life and supplied them to McDonald’s and KFC restaurants in July 2014, KFC’s single-store income began to decline continuously. Yum! China’s same-store sales fell by 16% in the third quarter of 2014, and almost all of them fell by double digits in the following three quarters. Parkson’s financial report for the second quarter of this year, just released in July this year, shows that the same-store sales of KFC in China increased by 2% year-on-year, but it actually climbed slowly from the low base of last year’s lowest valley. During the same period, the same-store sales of Pizza Hut in China shrank by 11%. Therefore, it is widely analyzed that the reason why foreign shareholders strongly demand Yum! Brands to spin off its business in China has something to do with the poor prospect.

  The "China Golden Period" of franchising may have passed.

  Franchising is an effective way for KFC to expand its business in the world. As early as 1993, it began to carry out franchising in China, and since 2000, it has only adopted the franchising mode of "not starting from scratch" in China. The so-called "not starting from scratch" means that KFC will hand over a mature and profitable restaurant to its franchisees. In this way, franchisees can put all their energy into the operation and management of stores without having to make preliminary preparations such as site selection, opening stores, recruiting and training employees. This greatly reduces the business risks of KFC franchisees. In the words of Su Jingshi, former president of Yum! China Restaurant Group Greater China, "franchisees can succeed only by maintaining." By this means, KFC has achieved rapid expansion in China, and the number of stores has reached nearly 5,000 by the end of last year.

  However, KFC has set a high threshold for joining, and the transfer fee for each restaurant is as high as 8 million yuan. After that, the going-concern expenses include the franchise fee accounting for 6% of the sales and the advertising sharing fee accounting for 5% of the sales, and the first agreement is signed for at least ten years. At this point, McDonald’s joining in China is exactly the same, and even the joining fee and cost-sharing ratio are exactly the same. This is obviously not a simple imitation of who, but a careful calculation based on a rigorous business model.

  In fact, no matter KFC or McDonald’s, its investment in the global business chain is more than the catering service itself, that is, it operates the store in a benign state by selecting a location. As can be seen from the income structure of the two catering giants, this part of the profits is far greater than their own stores. With KFC and McDonald’s reaching the scale of thousands of stores in China and gradually covering third-and fourth-tier cities, the blank market space in the future is getting smaller and smaller, and the golden period of realizing profits through joining and transferring has passed. Therefore, it may be the best time for them to "pack up and sell" their business in China.

  Although the supply of raw materials, as well as the annual brand use and marketing promotion expenses exceeding 10% of sales are still the long-term benefits they can enjoy, it is obviously only a decimal for them. Moreover, with the increasingly fierce competition in the catering market in China, the future sales potential of these foreign fast foods is not clear.

  The receiver may want to change the joining mode and continue to expand.

  Judging from the current Chinese takers of foreign fast food, whether it is Chunhua Capital or Ant Financial, or BTG, Sanpower and Sinochem, which are interested in bidding for McDonald’s China business, their real intention is probably not to directly participate in the catering industry, but to graft their current business to achieve profits in a new expansion mode.

  This can be seen from the caliber of Ant Financial. "Ant Financial will help Yum! China provide mobile payment services for its brands, including Alipay platform." In fact, although the online speculation of Ma Yun "finally achieved revenge for not being hired by KFC that year", in fact, Ma Yun is definitely a supporting role in this investment — — His total investment with Hu Zuliu of Chunhua Capital will only account for a few percent of Parkson China in the future. Even compared with Hu Zuliu, the $50 million invested by Ma Yun is too small, accounting for only a fraction of the total investment of $460 million.

  In fact, it can be seen from the fact that no real catering enterprise is willing to take over the business of KFC and McDonald’s in China that these two brands are more tools for the industry, which may also indicate that their future development in China will not be too exciting. Even some people in the industry believe that China KFC and McDonald’s, which have been abandoned by their parent companies, may embark on a development path in China that is divorced from stores in other countries in the world.

  I don’t know if it is the first move to merge into Ali. The Beijing Youth Daily reporter learned that KFC will officially enter Tmall on September 6. In the future, consumers can buy electronic coupons for KFC food in Tmall stores and then exchange them for corresponding foods in physical stores.

  Financial observation

  Kfcs are "old"?

  Although in many countries, KFC and McDonald’s are still regarded as the representatives of American fast food industry and even the symbols of American consumer culture, in fact, in the United States, more and more people have begun to diversify their choices, especially the opportunities for the younger generation of Americans to enter KFC are decreasing.

  In the first half of the year, the only cross-industry economic indicator of customer satisfaction in the United States, the American Customer Satisfaction Index, released the 2016 Restaurant Satisfaction Survey Report. It shows that the average satisfaction score of fast food restaurants in the United States this year is 79, but the scores of KFC and Pizza Hut under Yum! are below the average. McDonald’s ranked at the bottom of many participating fast food chain stores with a score of 69 points, and McDonald’s ranked at the bottom last year.

  As for the poor performance of KFC and McDonald’s, some American businessmen believe that although this does not mean that the food quality of KFC and McDonald’s has declined, they are "really old" in the eyes of American consumers and can no longer be the most typical representative of American fast food culture.

  In fact, in the China market, KFC and McDonald’s are also facing the same problem. With a new generation of young people becoming the main force of fast food consumption, McDonald’s and KFC are no longer their absolute first choice to experience foreign fast food, and a large number of other brands of fast food subdivide the China market. More crucially, no matter how the varieties cater to the taste of China population, the standard fried chicken, French fries, hamburgers and coke that KFC and McDonald’s take care of have become the global representatives of "junk food". More and more young families in China have kept their children away from such fast food restaurants, at least in first-and second-tier cities.

  For KFC and McDonald’s in China, the aura of standardization and trustworthiness that they were most proud of in the past has also been shattered with repeated food safety incidents. No matter Sudan red or fast-growing chicken, and then to the Shanghai Fuxi incident, these foreign fast foods have not been able to stay out of it.

Every year, about 300,000 people in China die from hepatitis B virus-related diseases.

    Hepatitis B is one of the infectious diseases with the highest incidence rate in China, and its mortality rate ranks among the top three reported infectious diseases in China. There are about 120 million hepatitis B virus carriers in China. The annual direct medical expenses for liver diseases in China are as high as more than 100 billion yuan. The incidence of hepatitis B in our province is also on the rise, and the incidence of hepatitis B is higher than the national average. The epidemic of hepatitis B is seriously endangering public health. Hepatitis B can be prevented, but the public doesn’t know enough about it. Therefore, it has become the unshirkable responsibility of the whole society to popularize the knowledge of hepatitis B prevention and improve their self-care awareness and self-protection ability.


    How big is the source of hepatitis B infection in China?


    On September 3, the reporter learned from the Provincial Center for Disease Control and Prevention (hereinafter referred to as the "Provincial Center for Disease Control and Prevention") that China has a large population and is a high-prevalence area of hepatitis B (hereinafter referred to as "hepatitis B"), and about 120 million people are carriers of hepatitis B virus. Among the hepatitis B virus carriers, about 20 million to 30 million people are chronic hepatitis B patients. Every year, about 300,000 people die from liver diseases related to hepatitis B virus infection, such as severe hepatitis, cirrhosis and hepatocellular carcinoma. In recent years, the incidence of hepatitis B in our province has also shown a gradual upward trend, and the incidence of hepatitis B is higher than the national average. From January to July this year alone, the incidence of hepatitis B ranked first in the number of legally reported infectious diseases in our province. From January to July this year, the incidence of hepatitis B in the province was 1248 cases, 785 cases, 1423 cases, 1225 cases, 1205 cases, 1237 cases and 1393 cases respectively.


    According to experts from the Provincial Center for Disease Control and Prevention, the source of infection of hepatitis B virus mainly comes from acute and chronic hepatitis B patients and hepatitis B virus carriers. Hepatitis B virus mainly propagates in human liver cells. Hepatitis B virus is also propagated in other organs and tissues of human body, such as endothelial cells, kidneys, white blood cells, pancreas, muscles and germ cells (referring to sperm) on the inner surface of small blood vessels, and a small amount of hepatitis B virus is found in muscles (smooth muscles) on intestines. Therefore, hepatitis B patients and hepatitis B virus carriers can’t supply blood, and their organs are not suitable for donation after death, because their organs all carry hepatitis B virus.


    The expert went on to say that the main ways of hepatitis B transmission include blood transmission, mother-to-child transmission and sexual transmission. Once hepatitis B virus enters the damaged skin mucosa, it can cause new infection. Mothers who are carriers of hepatitis B virus or patients with acute or chronic hepatitis B can spread to their own children in the fetal period, perinatal period and infancy. Experts estimate that 30%-40% of hepatitis B virus carriers in China originate from the spread of such mothers. This infection is very dangerous and serious. Because 90% of infected people can become hepatitis B virus carriers. The relationship between hepatitis B virus and liver cancer is very close, especially familial liver cancer is mostly related to hepatitis B virus infection. The mother is a carrier of hepatitis B virus, and most of her children are infected in childhood and become carriers of hepatitis B virus. It takes about 30-50 years for hepatitis B virus carriers to develop into liver cancer. Once infants and young children are infected with hepatitis B virus, they will become the main population with liver cancer in the future. Therefore, the first dose of hepatitis B vaccine must be given to the baby within 24 hours after birth in order to effectively block the infection of hepatitis B virus.


    What are the clinical symptoms of hepatitis B?


    According to experts from the provincial CDC, the average incubation period of hepatitis B is 6 weeks, but it may be as long as 6 months. Children are often asymptomatic after infection. But compared with adults, most children can become carriers of hepatitis B virus. Symptomatic hepatitis B patients will feel weak, have stomach upset and other flu-like symptoms, and also have dark urine color or grayish white feces, common jaundice (yellow skin or yellow sclera), and the symptoms can last for weeks or months. Most adults can fully recover from acute hepatitis B virus infection, but many children will become hepatitis B virus carriers. Patients with acute hepatitis B have lifelong immunity to the disease after rehabilitation (without becoming chronic carriers). If there are unexplained symptoms such as burnout, fatigue, loss of appetite, liver pain, hepatomegaly, tapping pain in liver area, jaundice, dark urine color, etc., liver disease examination and hepatitis B serological test should be done.


    How to prevent hepatitis B


    According to experts from the provincial CDC, two measures can be taken to prevent hepatitis B? Don’t use blood and blood products that haven’t been tested for hepatitis B in life and collective environment as much as possible, don’t go to black dens to donate blood, don’t have homosexual behavior and whoring behavior, don’t use unclean syringes, acupuncture needles, dental drills and endoscopes and other interventional medical instruments, and don’t share razors, ear needles, tattoo needles, toothbrushes and other instruments. In addition, it is to inoculate hepatitis B vaccine to improve its own immune antibody level.


    Hepatitis B vaccine is suitable for all people.


    Who is suitable for hepatitis B vaccination? According to experts from the provincial CDC, hepatitis B vaccine is also the only vaccine that can prevent liver cancer. Vaccination of hepatitis B vaccine is the core strategy to prevent hepatitis B. In addition to neonatal immunization, preschool children, adults and high-risk groups of hepatitis B should be vaccinated with hepatitis B vaccine.


    He said that the first group of people is newborns, which is the most important group to receive hepatitis B vaccine immunization. Because if you are infected by hepatitis B virus during this period, 90% of you can become asymptomatic infected and hepatitis B virus carriers, and the consequences are very serious. 30% of liver cancer related to hepatitis B virus infection comes from hepatitis B virus infection in newborns, and a large proportion of them develop into chronic hepatitis. Therefore, neonatal immunization is the most important thing to prevent hepatitis B. Since 2003, our government has provided free hepatitis B vaccine for newborns, and stipulated that all newborns must receive hepatitis B vaccine immunization, which is the right of children and the obligation of parents.


    The second group of people are children under 6 years old. Infants infected with hepatitis B are easy to become carriers of hepatitis B virus. The younger the infection age, the greater the probability of persistent infection. After such children are infected with hepatitis B virus, 30%-70% of them can also become carriers of hepatitis B virus, and they will easily develop into chronic hepatitis, cirrhosis and liver cancer in adulthood.


    The third group of people are doctors, especially doctors in surgery, obstetrics and gynecology, dentistry and otolaryngology, laboratory workers engaged in serum testing and all nurses. Anyone who has not been infected with hepatitis B virus should be vaccinated. Besides protecting yourself, it can also protect the safety of patients. In addition, if there are hepatitis B patients or hepatitis B virus carriers at home, their family members should be vaccinated against hepatitis B to avoid infection.


    The fourth group of people are those who are engaged in heavy physical labor and are easy to cause labor injuries.


    The fifth group of people is people with low immune function. For example, after tumor surgery, people who take immunosuppressive drugs for a long time, renal dialysis patients, and blood patients who often need blood transfusion and blood products are in poor health and have low resistance. Once they are infected with hepatitis B virus, the consequences are very serious, so they should be vaccinated with high doses of hepatitis B vaccine.


    The sixth group of people are the army, college students of certain majors, etc. However, there are also some people who can’t get hepatitis B vaccine and don’t need it. If a person with a fever can’t be vaccinated, wait until his fever has gone down. Secondly, people with allergies, that is, people who are allergic to many things should use hepatitis B vaccine with caution. There are already protective antibodies in the body, and people with high levels do not need to be immunized again. However, if the antibody level is very low, it is still a suitable target for vaccine immunization.


    Three needles, protect the child’s life!


    On September 3rd, the reporter learned that according to the actual situation in our province, the Provincial Health Department, in cooperation with the China Hepatitis Prevention and Treatment Foundation, will give free hepatitis B vaccine to 500,000 school-age children in Haidong, Haixi and Yushu from September this year to May next year, so that more than 95% of school-age children in primary schools in the province can get free hepatitis B vaccination, thus making Qinghai one of the provinces that have completed hepatitis B vaccination for school-age children nationwide. Therefore, experts from relevant departments in our province especially remind the public that hepatitis B can evolve into chronic hepatitis, cirrhosis and liver cancer, and hepatitis B vaccine can indirectly prevent liver cancer. Therefore, after three shots of hepatitis B vaccine are given in newborns and childhood, chronic hepatitis, liver cirrhosis and liver cancer can be prevented. After the child is born, he should be given three injections according to the procedure of 0, 1 and 6 months stipulated by the national immunization plan, that is, the first injection should be given within 24 hours after birth, the second injection should be given at one month and the third injection should be given at six months. Adults and children can be vaccinated according to the procedures of 0, 1 and 6 months, which can protect you and your child’s life. (Author: Wang Xiaohong)
