CCTV News:Since the beginning of this year, there have been explosions of companies in the A-share market, such as Buchang Pharmaceutical and Xincheng Holdings. The stock prices have been falling continuously, and investors have suffered heavy losses. In the past two days, dividends have also exploded. Dividends were originally a good thing, earning money to return investors, but this dividend was the first time I saw it.

　　On the afternoon of July 19th, Fu Jen Pharmaceutical announced that due to funding arrangements, cash dividends could not be paid according to the original plan. According to the annual dividend plan of Furen Pharmaceutical in 2018, it is planned to distribute a total cash dividend of 62,715,800 yuan. The data shows that as of the end of the first quarter of 2019, the balance of monetary funds on Furen Pharmaceutical’s account was 1.816 billion yuan.

　　Some analysts in the industry believe that Fu Jen Pharmaceutical’s financial report data in recent years violates common sense and is suspected of serious fraud.

　　Furen Pharmaceutical has a thunder account of 1.8 billion but has no money to pay dividends.

　　Fu Jen Pharmaceutical announced on July 19th that due to financial arrangements, the company failed to complete the transfer of cash dividends in accordance with relevant regulations, and could not pay cash dividends as originally planned. The "iron rooster" who didn’t pay dividends for 20 years finally got a bonus last year. This year, it is clear that there are 1.8 billion monetary funds in the account in the first quarter, but even 60 million can’t be separated. I believe that after the resumption of trading, the stock price pressure will be great.

　　On July 15th, Dong ‘e Ejiao announced its semi-annual performance forecast, and its net profit decreased by 75% to 79% compared with the same period of last year. On July 12th, Han’s laser forecast net profit decreased by 60%-65% year-on-year. The market was shocked, and Baima would step on thunder, and its share price plummeted.

　　Another example is the former Xincheng Holdings and Buchang Pharmaceutical. Because the scandal of the company’s chairman was exposed, the stock price fell.

　　There are also people who are particularly concerned about Kangmei Pharmaceutical and Kangdexin. Because of their alleged financial fraud, their share prices have fallen by only a fraction. In addition, in the past two years, Shapu Aisi and Erkang Pharmaceutical, various emergencies have caused listed companies to explode.

　　The proportion of R&D in explosive pharmaceutical enterprises is low, and the sales expenses are high.

　　Further observation of so many companies that explode mines, among which pharmaceutical companies account for a lot. Simply analyzing these companies, Furen Pharmaceutical spent 230 million yuan on R&D and 820 million yuan on sales in 2018, accounting for 3.6% and 13.0% of revenue respectively.

　　In 2018, Buchang Pharmaceutical spent 480 million yuan on R&D and 8.04 billion yuan on sales, accounting for 3.5% and 58.9% of revenue respectively.

　　Generally speaking, the R&D expenses of these companies are relatively low, but on the other hand, the sales expenses are relatively high, such as Buchang Pharmaceutical. Nearly 60% of the operating income is used for sales, and I don’t know where the money has gone. Many investors believe that if products are not competitive, they can only strengthen sales and even play the edge ball.

　　Pharmaceutical companies generally have a high gross profit margin, but apart from the relevant employees, in fact, many people simply don’t understand the company, and they can’t know the actual curative effect of the products, and how the actual sales are. For example, some Chinese medicine companies have unclear curative effects due to historical reasons. Recently, many Chinese medicine injections have been restricted, and related listed companies will be affected.

　　Lujiazui view:

　　For investors, if they see pharmaceutical companies with low R&D expenses and high sales expenses, they should be careful to avoid stepping on thunder.

　　Xinhua News Agency, Beijing, July 20th Special feature: The international community does not believe the lie of "China stealing intellectual property rights" concocted by the United States.

　　Xinhua news agency reporter

　　In line with its suppression of China’s foreign policy and economy, the United States recently again speculated on the so-called "China’s theft of intellectual property rights". Some media reported that Nathaniel Fick, the ambassador-at-large in charge of cyberspace and digital policy in the United States, claimed that China promoted the development of domestic artificial intelligence and other technologies by stealing intellectual property rights.

　　However, many international authoritative experts pointed out that China’s scientific and technological innovation is obvious to all, and there is no doubt about the respect and protection of intellectual property rights. The argument that "China stole intellectual property rights" has no factual basis and is a political trick with ulterior motives.

　　For decades, thanks to the attention of the China Municipal Government, China has made historic achievements and progress in the field of intellectual property rights, and its global ranking in the field of innovation has steadily increased, ranking among the global innovation leaders. These achievements have been highly recognized by international organizations such as the World Intellectual Property Organization and business circles, and the lies fabricated by some people in the West are hard to confuse people.

　　Innovation achievements attract worldwide attention.

　　World Intellectual Property Indicators is the authoritative annual report of the World Intellectual Property Organization to analyze global intellectual property activities. According to the latest annual report for 2022, despite the economic recession caused by the COVID-19 epidemic, the number of applications for intellectual property rights of patents, trademarks and designs in the world reached a new high in 2021, thanks to the growth of applications from Asian countries such as China, South Korea and India.

　　The report compiles data from about 150 countries and regions, among which China National Intellectual Property Administration, China accepted 1.59 million patent applications in 2021, ranking first. China also ranks first in the world in terms of the number of trademark applications and industrial design applications.

　　In addition to the number of intellectual property applications ranking first in the world in recent years, China’s global ranking in the field of innovation has also steadily improved. The annual report of Global Innovation Index released by the World Intellectual Property Organization continuously tracks the performance of global innovative economies and ranks them. China joined the index in 2013, and ranked 35th at that time. Since then, its ranking has improved year by year. Ranked 14th, 12th and 11th respectively in 2020, 2021 and 2022.

　　Deng Hongsen, Director-General of the World Intellectual Property Organization, said that China regards innovation as the engine of growth, and the China government attaches great importance to intellectual property rights, which can coordinate the formulation of intellectual property policies and other factors in the development process. China has created an innovation ecosystem in an all-round way, which is an important factor for China’s success.

　　The innovation ecology is improving day by day.

　　Saha Vinsch-Vincent, head of the Economics and Data Analysis Department of the World Intellectual Property Organization, believes that China has become one of the global innovation leaders, thanks to its consistent innovation policy planning and implementation over the years and increasing investment in education, science and technology. "More importantly, China has the ability to transform policies and inputs that are conducive to innovation into achievements such as intellectual property rights, innovative products and high-tech exports."

　　"The speed of establishing well-known high-tech companies in China is impressive. Most of these companies are located in industries such as information and communication technology and white goods. They have long focused on inventing, applying for and using intellectual property rights and are well-known in the world." Vince-Vincent said.

　　He emphasized that the number of patents per unit GDP in China is higher than that in Japan, Germany and the United States, which is even more impressive if calculated by the total number of patents, as is the number of trademarks and industrial designs per unit GDP.

　　More important than ranking, China has been constantly pursuing a sound and green innovation ecosystem, which has also established full ties with innovation subjects in other countries. When it comes to China’s steady rise in the ranking of innovation index, Wen Shi-Vincent thinks it is natural, because China’s policy makers have been continuously learning and constantly improving their innovation policies.

　　"We can see China’s efforts to promote improvement, whether in strengthening the connection between science and industry, in further establishing innovation clusters in China, or in putting China’s huge stock of intellectual property applications into practice through commercialization or cross-licensing." He said.

　　Francis Gurry, former director-general of the World Intellectual Property Organization, believes that China’s economy is undergoing a large-scale structural transformation from labor-intensive manufacturing to knowledge-intensive industries, and innovation is the key to the success of this transformation.

　　"This top-down policy is supported by the whole country, including state-owned enterprises, private enterprises, universities and research institutions." Gao Rui said that the number of scientific publications in China keeps rising, and the number of international patent applications from China keeps increasing. "All indicators are positive and follow a consistent trend. This well-planned innovative policy, which is highly concerned by the leadership, is a key factor for China’s success. "

　　American lies are untenable.

　　Many experts believe that the so-called "China’s theft of intellectual property rights" lies have resurfaced, and there are ulterior political motives behind them. This old prejudice is completely inconsistent with the facts.

　　William jones, president of the Washington branch of Global Strategic Information magazine, said: "Most of them revolve around the so-called ‘ Technical theft ’ The hype is just a political stunt, aimed at weakening the progress made by China in the past decades. China is in an important process of industrialization, with a large number of local talents and government support, and has made remarkable progress. "

　　Robert Atkinson, chairman of the American Information Technology and Innovation Foundation, said: "Think of China as ‘ Plagiarist ’ It is wrong, China can and is innovating. "

　　In the field of scientific and technological innovation, experts believe that the achievements made by China are obvious to all. China has been at the forefront of the world in many fields, such as 5G, mobile e-commerce, mobile payment, smart phone, new energy technology and financial technology, and has also made important progress in artificial intelligence, electric transportation and autonomous driving.

　　"Some people still think that China is good at ‘ Copy ’ It is an old view that foreign technology rather than leading technological innovation. In the next few years, the progress of China’s technological capabilities will have a profound impact on the international market and the global competition pattern. " Sean Randolf, senior director of the Economic Research Institute of the U.S. Bay Area Council, said in his report "China Innovation: China’s Technological Future and Its Significance to Silicon Valley".

　　Cecilia Bornefeld-Dahl, Director-General of Digital Europe, said that China has made many positive efforts in protecting intellectual property rights, "and I also know that China will do more in this regard".

　　The Australian Financial Review recently published a commentary by Michael Wesley, Vice President of Melbourne University, saying that the idea of reducing exchanges with universities and scholars in China on the grounds of worrying about the disclosure of intellectual property rights is both limited and misleading. China researchers don’t need to cooperate to "steal" Australian intellectual property rights. According to the latest research cited by American Science magazine, researchers in China account for the highest proportion of the most cited scientific papers.

　　The data shows that in 2022, the proportion of basic research funds to R&D funds in China is 6.32%, which has been stable above 6% for four consecutive years.

　　History and facts have fully proved that China’s achievements in scientific and technological innovation were not stolen or snatched, but achieved through self-reliance and hard struggle. It is totally groundless and absurd to accuse China of "stealing" intellectual property rights for its development.

Restarted version of Ghost Boy’s Return to Soul

1905 movie network news The restarted version of "Ghost Baby Back to Soul" recently exposed a Taiwanese Chinese preview. Although this restarted version in 2019 is similar to the previous story in 1988, both of which tell the story of the ghost girl Chuck possessed by a murderer killing in a little boy’s home, it can be seen from the trailer that the main horror element of the film is innovative.

　

The trailer shows that "Ghost Baby" is a toy, but because its system can control its own intelligent systems, including refrigerators, stereos, mobile phones, cars and even drones, its killing game can spread to all aspects of life, and bloody tragedies continue to occur. At the end of the trailer, Chuck, the ghost who plays "Luke Skywalker" in the series, finally appeared. "Good night, Andy," an old and cruel voice sounded, which was chilling.

　

In 1988, Ghost Baby’s Return to Soul was one of the classic horror films in 1980s, directed by Tom Hollander and co-written by Don Mancini. Chuck, who is possessed by a murderer in the film, has the shape of a doll and is bought by a young mother and given to her son. Chuck learns that if he wants to get rid of the doll’s body, he must exchange his body with the first person who knows his true identity, which is also the beginning of the boy’s nightmare. The "Ghost Baby" in the film, which combines the cuteness of a doll with the viciousness of a murderer, has become an important image in the history of horror films. So far, the series has shot the seventh sequel.

　

The re-released version of Ghostbusters is directed by Lars Kleiberg, and the original series of screenwriters Don Mancini is the screenwriter, starring Bryan Terry Henry, Gabriel Bateman, Beatrice Kiso, Ty Concilio and others. It will be released in North America on June 21st.

High-resolution environmental records in different areas of the plateau have been established, revealing the characteristics of climate and environment changes in the past 20 thousand years, especially in the last 2000 years. The relationship between the uplift of Himalayas and Qinghai-Tibet Plateau and Asian monsoon climate is studied comprehensively and systematically for the first time. The results show that the uplift of the Qinghai-Tibet Plateau 10-8 million years ago led to the emergence of the Asian monsoon, and the accelerated uplift of the Qinghai-Tibet Plateau 3.6-2.6 million years ago laid the basic framework of the Asian monsoon climate. It shows that the evolution of Asian monsoon is closely related to the periodic uplift of plateau.

　　　　13. Many breakthroughs have been made in the deep subduction of the mainland.

　　　　The continuous material composition, three-dimensional structure, material exchange between crust and mantle and geophysical state in the deep part of plate convergence boundary are revealed. It is proved that there was an important geological event in geological history when the plate carried a huge amount of material and dived deep into the mantle below 100 kilometers. It is found that the instability caused by dehydration of structural water (OH) in eclogite minerals can induce fractures and cause high-temperature earthquakes, which explains the cause of deep earthquakes in mantle transition zone. This achievement was published in NATURE magazine in 2004.

　　　　14. Marine scientific research

　　　　The theoretical framework of China’s offshore ecosystem dynamics is established, and it is the first time to establish a theoretical framework based on the ecosystem level. The quota fishing assessment and management model, taking fish as an example, found that the strategy of Daphnia sinensis to spend the summer in the shallow sea of temperate continental shelf is considered as one of the representative research achievements since the implementation of the international Global Marine Ecosystem Dynamics (GLOBEC) plan. At the invitation of members of the GLOBEC Scientific Steering Committee and the North Pacific Scientific Organization (PICES), it was reported at international scientific conferences many times, which had a great impact.

In the past four years, with the continuous promotion of the construction of Hengqin Guangdong-Macao deep cooperation zone and the continuous improvement of the software and hardware facilities at Hengqin Port, the personnel exchanges between Hengqin and Macao have continuously set a new record for customs clearance, and the total number of entry-exit personnel at the port has exceeded 48 million.

The reporter learned that the average daily passenger flow and traffic volume of Hengqin Port this year reached 57,000 passengers and 6,000 vehicles respectively, which doubled compared with 25,000 passengers and 2,700 vehicles four years ago. At the same time, this year, the single-day passenger flow at Hengqin Port exceeded 86,000, and the traffic volume exceeded 7,200, both of which were the highest levels since the opening of the new Hengqin Port. The high convenience of going in and out of Hengqin is gradually changing the living habits of Macao residents, and the demand of Hong Kong and Macao residents to go to Hengqin for home ownership, entrepreneurship and leisure tourism is also growing.

The deputy stationmaster of Hengqin Border Inspection Station of Zhuhai Border Inspection Station once introduced that, according to statistics, among the inbound and outbound personnel, about 39% are from the mainland who go to Australia for employment and study, about 26% are from Hong Kong and Macao residents, and about 24% are from the mainland who go to Australia. The characteristics of the people’s livelihood port of Hengqin Port "seven points for people’s livelihood and three points for tourists" are increasingly prominent.

In recent years, the infrastructure of the new Hengqin Port has been continuously improved, and the vehicle joint inspection system and the vehicle attendant inspection and release hall of five units in Guangdong and Macao, the first in China, have been launched successively, achieving highly convenient customs clearance for vehicles and vehicle attendants. At present, the customs clearance of goods and transport vehicles at Hengqin Port is being resumed in an orderly manner in stages, and the policy dividend is fully released to fully improve the efficiency of customs clearance services. At the same time, Hengqin Border Inspection Station has accelerated the construction of an intelligent car body inspection system, continuously optimized the customs clearance process of "Qin-Ao Tour Group" and "Frequent Traveler", and further created a highly convenient customs clearance environment for personnel to enter and leave.

Zeng Xiang said that since the beginning of this year, there have been more than 13 million passengers and about 1.4 million vehicles entering and leaving through Hengqin Port. It is expected that the total number of passengers entering and leaving the country will exceed 20 million and the traffic volume will exceed 2 million during the year. Facing the increasing passenger flow, Hengqin Border Inspection Station will continue to improve customs clearance services, optimize personnel customs clearance mode, and contribute border inspection wisdom to the rapid development of Qin-Macao integration.

As of August 17, the number of people entering and leaving Baiyun Port reached a five-year high this year.
