Today, I want to talk with you about this kind of marine life. There is a famous distant relative, the Yangtze finless porpoise, but it is not known at all. The sea pig, pig fish and river pig are folk names for it. It is also known as the "East Asian finless porpoise", commonly known as the seawater finless porpoise. It is a national endangered second-class wild aquatic protected animal, which is listed as endangered (En) in the IUCN species list, and its number is on the decline. East Asian finless porpoises like to live in shallow coastal waters and the waters where salt and fresh water meet. They are mainly distributed in the East China Sea, the Yellow Sea and Bohai Sea north of the Taiwan Province Strait, and the northern waters of South Korea and Japan.

When it comes to the East Asian finless porpoise, you can find a lot of information released by Ren Zengying, the "river guardian" on the Internet. From November 23rd, 2012 to now, Ren Zengying paid special attention to the fate of the East Asian finless porpoise for eight years, and she was also sad and helpless for eight years. According to Ren Zengying’s completely unscientific conservative estimation, the number of unexplained deaths of East Asian finless porpoises in the Yellow Sea and Bohai Sea off the coast of Shandong Province ranges from 500 to 1,000 each year. These figures make her so worried, but there is a deep sense of powerlessness. Ren Zengying even lamented that perhaps the fate of the seawater finless porpoise can attract some people’s attention only if there is a bigger tragic event.

What is more tragic than the report is the reality.

In the interview, Ren Zengying told us that in the media reports, tourists and fishermen occasionally saw the news that the East Asian finless porpoise was stranded and died, but the reality was even more severe. In July 2013, a fishing boat captain told her that they threw away 18 dead East Asian finless porpoises on a trip to sea. On December 24, 2014, a local volunteer contacted her urgently and found four dried East Asian finless porpoises. Not to mention, videos can still be seen on the Internet. In November 2013, the East Asian finless porpoise was stripped with only one dolphin skin near Jinshui Bridge in Yantai. In 2019, as of March 23, Ren Zengying received 31 cases of death of sea water finless porpoises. "Although I have never seen the real East Asian finless porpoise, it is at the second scene or even the N-th scene, whenever fishermen’s friends and volunteers tell me where to find the East Asian finless porpoise, I will contact the local fishery administration department, propaganda department and media for the first time. After a long time, everyone gave me a nickname’ the goddess of dolphin protection’, and everyone used to find that the finless porpoise reported to me first, but the reality was always so gloomy and cruel. "

The dead finless porpoise was skinned by the sea

The sea finless porpoise is also a finless porpoise.

The most embarrassing thing is that many people don’t know or even know that there is an East Asian finless porpoise. Some media have mistakenly published and reprinted the death scene of the "East Asian finless porpoise" in the Bohai Sea as the death news of the "Yangtze finless porpoise", which caused a social sensation. Looking at the horror of the death of the "East Asian finless porpoise" in the report, Ren Zengying was very tearless. Therefore, "the sea finless porpoise is also a finless porpoise" has become Ren Zengying’s propaganda slogan of "eight years is like one day". "What I want to do is to at least let everyone know about the existence of the East Asian finless porpoise, and then pay attention to the East Asian finless porpoise through search, and then there is the possibility of protecting the East Asian finless porpoise. Today, if you search for the East Asian finless porpoise on the Internet, there is no very accurate and scientific research report, which may be the key to the East Asian finless porpoise not being recognized by the public. " In addition to widely publicizing that "the seawater finless porpoise is also a finless porpoise" in the coastal waters, Ren Zengying often popularizes the relevant knowledge of the East Asian finless porpoise for primary and secondary school students on the platform invited by the school to carry out popular science education on coastal wetland protection, and explains the survival dilemma faced by the East Asian finless porpoise.

It’s not delicious and can’t be eaten.

In fact, in addition to natural death, sometimes the East Asian finless porpoise that died near the shore was "accidentally caught" by fishermen. In the process of fishing, once the East Asian finless porpoise crashes into the fishing net, it is difficult to break free, and it will slowly suffocate and die. In the eyes of fishermen, the East Asian finless porpoise is not only a national second-class endangered protected animal, but also really unpalatable and has almost no economic value. Earlier, there was an illegal act of stealing the East Asian finless porpoise and selling it as fish in the market. The price tag was a catty of 5 yuan, but it could not catch up with the price of a catty of clams. Therefore, in the mouth of fishermen, the East Asian finless porpoise will be called "sea pig". Therefore, once the East Asian finless porpoise is caught by mistake, the most common practice may be to throw it directly back into the sea. "This thing is not delicious, and it has no economic value. Our cabin space is limited. Its head is too big, and it weighs more than 200 kilograms. Just throw it into the sea." This is the fisherman’s explanation to Ren Zengying.

Why don’t you know the East Asian finless porpoise?

As a migratory creature, the migration route of the East Asian finless porpoise has not been determined yet, which can be said to be elusive. This has something to do with China’s long coastline. Once investigation and study are carried out, there may be some relations between large input and small output. However, combined with long-term observation and data analysis, Ren Zengying speculated that the area at the junction of the Yellow River estuary and the sea may be the breeding ground of the East Asian finless porpoise. In Shandong Peninsula, the estuaries of the mother river in several coastal cities, twenty years ago, were mostly excellent observation points for East Asian finless porpoises. This is because the East Asian finless porpoise likes to live in shallow coastal waters and the waters where salt and fresh water meet, so the population survival of the East Asian finless porpoise will be regarded as one of the weathervanes of seawater pollution. Now talking about this kind of "sea pig", fishermen sigh a lot, which is hard to see in the river.

However, the public generally lacks understanding of the East Asian finless porpoise, which in itself will have an improper impact on the rescue and rescue of the East Asian finless porpoise. For example, many people don’t know how to rescue the East Asian finless porpoise when it is found, which rescue phone to call, and even don’t know that the East Asian finless porpoise can’t be easily transported to avoid secondary injury. These will be the focus of the public welfare project "East Asian finless porpoise Guardian Program" to promote popular science.

In the interview, Ren Zengying repeated a sentence many times-"The sea water finless porpoise is also a finless porpoise", hoping that all sectors of society can pay attention to the sea water finless porpoise as they pay attention to the "smiling angel" Yangtze finless porpoise, and hope that the sea water finless porpoise can also be treated as a national second-class endangered wild aquatic protected animal, and get due attention and protection from all sectors of society.

We will also invite experts and scholars in the industry to discuss how to observe and protect the East Asian finless porpoise better and more scientifically, and gradually apply the research results to our project of "Protecting the East Asian finless porpoise".

We know that,

When our little bodies,

Lying motionless on the fishing boat deck.

People with heartburn will continue to grieve,

People who are indifferent will continue to be indifferent.

……

Mom and dad often reminisce about the good old days.

Unfortunately, we can’t experience it.

Although we can live in fresh water and sea water,

However, we can’t find the way back to the river to play.

We can’t even see the original coastal zone.

—— Excerpt from "Ren Zengying’s Letter Graffiti" on October 15, 2018

Over the past few days, netizens have paid close attention to the living and health conditions of the giant pandas Meixiang, Tiantian and Little Miracle in the Smithsonian National Zoo.

China Giant Panda Conservation Research Center recently sent experts to Smithsonian National Zoo. After on-site verification by experts, the giant panda breeding management and disease prevention and control in Smithsonian National Zoo all meet the standards and requirements of giant panda breeding management and health management, and the giant pandas Meixiang, Tiantian and Little Miracle are generally in good health.

At present, "Little Miracle" is in good health, growing well and weighing over 90kg. Under the professional treatment and careful care of the Smithsonian National Zoo, the common diseases of the giant pandas Meixiang and Tiantian, such as hypertension and arthritis, have been well controlled. Ascites is common in elderly giant pandas. There was mild ascites in Meixiang, which has been effectively controlled after treatment, and health monitoring will continue to be strengthened in the future.

Since the birth of "Little Miracle" in 2020, China and the United States have made it clear that Mei Xiang and Tian Tian will no longer participate in breeding, and the Smithsonian National Zoo will no longer conduct artificial sperm collection and artificial insemination on Mei Xiang and Tian Tian. The giant panda "Little Miracle" is not yet an adult, and its growth and development are not yet mature, so it cannot participate in reproduction.

Over the past 22 years, China and the United States have carried out fruitful cooperation in panda protection and management, breeding, scientific research, disease prevention and control, and public education. The two sides have jointly bred four giant panda cubs, published hundreds of scientific research papers and jointly held several academic exchange and training activities. The Smithsonian National Zoo has more than 2 million visitors every year, and the online and offline public education has covered hundreds of millions of people worldwide, which has promoted mutual understanding and friendship between Chinese and foreign people.

　　Modern industrial system is the material and technical foundation of modern countries. Report to the 20th CPC National Congress of the Communist Party of China put forward the important task of building a modern industrial system. The first meeting of the 20th Central Committee of Finance and Economics emphasized the "five persistences" in accelerating the construction of a modern industrial system, namely, persisting in focusing on the real economy, striving for progress steadily and step by step, persisting in the three-time industrial integration and development, persisting in promoting the transformation and upgrading of traditional industries, and persisting in open cooperation. This is an action guide for building a modern industrial system with integrity, advancement and safety in the future.

　　To build a modern industrial system, we must first accurately grasp the era connotation of this concept. On the whole, the modern industrial system should have at least three main characteristics. One is integrity. Integrity not only refers to the complete industrial categories, but also refers to the complete production capacity of high-end products within the industry. In addition, integrity also refers to adapting to the characteristics of China’s huge population, and the labor-intensive industries are fully developed and can provide sufficient jobs. The second is the advanced nature. Advanced nature not only refers to the high level of production technology and management, but also refers to the strong industrial competitiveness, which can support industrial upgrading under the current situation of two-way extrusion of developed and developing countries in China. In addition, it can also provide high-level factor returns and effectively promote common prosperity. The third is security. Safety means not only being able to achieve a high level of self-reliance without highlighting shortcomings and weak links, but also that key resources such as grain, energy and minerals can meet development needs, and that the industrial system should be environmentally friendly and take the road of sustainable development. Generally speaking, the three characteristics of "integrity, advancement and safety" fully reveal the important connotation and development requirements of modern industrial system.

　　According to the era connotation of modern industrial system and the current situation of industrial development in China, we need to grasp five important principles to accelerate the construction of modern industrial system supported by real economy.

　　First, insist on focusing on the real economy and prevent it from being divorced from reality. It is the key to build a modern industrial system to optimize the allocation of production factors and allocate high-quality production factors to the most critical industries. The nature of capital is to flow to the place where the highest return can be obtained, and its sensitive sense of smell can always compare the average profit rate of different industries. This natural profit-seeking, that is, "from the real to the virtual" or "from the virtual to the real" flow valve. It is the real economy that really creates wealth for the society, creates more jobs and opens up the track of scientific and technological innovation. The real economy is the foundation of the country and is of great significance to maintaining long-term economic prosperity and social stability. China started from the real economy, and it also depends on the real economy to move towards the future. At any time, we can’t "break away from reality". The most fundamental thing is to make the real economy grow stronger and make the manufacturing industry, especially the advanced manufacturing industry, profitable and promising.

　　To prevent the reality from becoming illusory, we must first effectively improve the benefits of the real economy and enhance its attractiveness to factors such as funds and talents. Manufacturing industry is the main industry participating in international competition and the core of the real economy. In order to comprehensively improve the efficiency level of manufacturing industry, we should not only attach importance to the "addition" policy, support and guide enterprises to strengthen innovation, develop with specialization and novelty, and enhance the differentiation of products and services, but also combine the "subtraction" measures, especially to guide low-quality and inefficient enterprises to withdraw from the market in time, shape a reasonable competitive market structure, and supplement it with the policy of expanding demand to improve pertinence and directness. Secondly, while strengthening "reality", we must also make up "emptiness". In the financial field, it is necessary to improve the diversified and efficient financial service system and guide finance to better play its role in serving the real economy. It is necessary to further deepen systematic, institutional and rule-of-law reforms, gradually and steadily solve the obstacles that affect the stability and healthy development of the capital market, so that abundant social funds can be more effectively invested in the real economy and provide more solid industrial support for high-quality development.

　　Second, we should persist in striving for progress steadily and step by step, and we should not be greedy for foreign countries. Building an advanced modern industrial system does not mean that all localities should develop high-tech industries at the same time. Emerging industries, high-tech industries and major projects are growing rapidly and have good development prospects, which have a great pulling effect on the local economy, and often become the focus of attention in various places. However, it is also easy for all places to rush headlong into the herd and compete excessively, and a few places succeed, while most places invest a lot but fail to achieve benefits. Although some places or cities have succeeded in developing high-tech industries by leaps and bounds, they do not have simple replication, and blindly launching projects without considering the actual situation may produce fallacy of composition. To implement the requirements of striving for progress steadily and step by step, the core is to give full play to the different roles of the market and the government in industrial development. Local governments need to formulate industrial development plans to clarify and guide the upgrading and development of local industries, but the focus should be on constantly improving market supervision, strengthening services to enterprises, strengthening planning guidance and shaping a better business environment. Enterprises are the main body of investment decision-making and self-financing. The government can’t take the place of independent decision-making by enterprises, and it can’t attract projects with so-called preferential subsidies for "assessing performance".

　　The third is to adhere to the integration and development of three industries and avoid separation and opposition. There is an inherent balance among the three industries, so we can’t unilaterally emphasize the development of any one industry. China is a unified big market, where goods and services circulate efficiently and help each other, and the industrial development of each region should mainly follow the principles of comparative advantage and efficiency priority. From various places, we should neither unilaterally pursue the proportion of tertiary industry and simply implement "retreat from two to three", nor unilaterally emphasize the proportion of manufacturing industry and inhibit the development of service industry. At present, we should pay more attention to the new trend of the integration and development of various industries. With the rapid development of the new generation of information technology and digital technology, its empowerment effect on various industries is more significant, and the traditional boundaries between many industries are also blurred. For example, in many typical manufacturing enterprises, the value-added from R&D, design, brand image, after-sales and other service links has greatly exceeded the manufacturing link. The deep integration of modern service industry with advanced manufacturing industry and modern agriculture has become an important direction of industrial upgrading. In guiding industrial development, all localities should fully consider the inherent requirements of the integrated development of local pillar industries, upstream and downstream industries and related industries, and reserve sufficient space and resources for the development of related industries.

　　Fourth, we should persist in promoting the transformation and upgrading of traditional industries and should not simply quit as "low-end industries". Traditional industries are the base of modern industrial system, and the transformation and upgrading of traditional industries are directly related to the overall construction of modern industrial system. In the process of building a modern industrial system, China must always attach importance to the development of traditional industries. This is the requirement of maintaining and enhancing China’s industrial competitiveness. At present, China’s traditional low-cost advantages are weakening, and the establishment of competitive advantages such as technology and brand is not achieved overnight. The complete industrial system and strong supporting capacity are important sources of China’s industrial international competitiveness for a long time. The simple withdrawal of traditional industries will directly damage China’s industrial integrity, reduce its supporting capacity and ultimately weaken China’s international competitiveness. At the same time, the new round of scientific and technological revolution and industrial transformation has also brought new opportunities to improve the efficiency and international competitiveness of traditional industries. Many traditional industries can become advanced manufacturing industries after transformation and can have a longer development period. To promote the transformation and upgrading of traditional industries, we should continue to increase support for the digital intelligence and green transformation of traditional manufacturing industries, and solve the problems of low profit margin and weak self-upgrading ability of traditional industries; In the process of promoting industrial transformation and upgrading, local governments should attach great importance to the development of traditional industries with cluster effect, provide support and guarantee for the development of these traditional industries, and prevent simplification from retreating.

　　The fifth is to adhere to open cooperation and not build a car behind closed doors. Persisting in opening to the outside world is an important experience of China’s rapid economic development in the past. Through "bringing in" and "going out", China not only introduced important capital and technology, but also participated in competition and learning in the global market, which promoted the product quality and competitiveness. Continuous open cooperation is an inherent meaning of building a modern industrial system and an inevitable requirement for achieving high-quality development. It should be clearly seen that the key core technologies can’t wait or not, and the key links of the industrial chain and supply chain must be mastered by China itself, but we can’t take the old road of closed development. Only by adhering to a high level of opening to the outside world and always keeping the domestic market fully open to domestic and foreign enterprises can we deeply participate in the global industrial division and cooperation, maximize the absorption of foreign advanced achievements, accelerate the pace of innovation, give full play to China’s super-large-scale market advantages and strive for a better external environment, and also better expand the potential of external demand, promote industrial upgrading and better build a modern industrial system.
