The above "Seven Laws" is not the ink of any literary master, but by a paleontologist, who is the first director of the Institute of Paleontology and Paleoanthropology in China, and academician Yang Zhongjian, who is known as the "founder of Chinese paleovertebrate zoology".
China is the country with the most named dinosaurs in the world, of which nearly ten kinds of dinosaurs are directly or indirectly named after Academician Yang Zhongjian, which contains the respect and nostalgia of China's dinosaur researchers for Yang Lao. In the world-famous British Museum, Yang Lao is also the only Asian scientist whose photographs hang side by side with photos of darwin, Owen and other scientific giants.
So, what kind of legendary experience did he have in his life?
Mr. Yang Zhongjian, a chinese paleontologist (UC Headlines)
Responsible for the excavation of the Zhoukoudian Beijing Ape Man Site
Yang Zhongjian was born on June 1, 1897 in Longtanbao (present-day Shaohua Township), Hua County, Shaanxi Province. Although he grew up in the countryside, Yang Zhongjian's family was really unusual, and his father Yang Songxuan was a famous educator in the late Qing Dynasty, a member of the Shaanxi Branch of the Chinese League Association, and single-handedly founded the private Xianlin Middle School (the predecessor of Xianlin Middle School). With a father who became an educator, Yang Zhongjian naturally had better learning conditions than other children of his generation, and successfully became a primary and secondary school curriculum and successfully entered the geology department of Peking University. He became acquainted with the famous geologist Li Siguang, and then went to Germany to study under his recommendation and began to specialize in vertebrate paleozoology.

In 1927, Yang Zhongjian obtained a doctorate certificate from the University of Munich with his thesis "Rodent Fossils in Northern China" and was given the opportunity to study in Western European countries. A year later, Yang Zhongjian returned to China and was elected to work at the Central Geological Survey to work on the excavation of the Zhoukoudian site, during which time his assistant Pei Wenzhong discovered the skull of a "Peking man" in it. It was precisely because of this discovery that shocked China and foreign countries that the Central Geological Survey ordered the establishment of the "Cenozoic Research Laboratory" in 1929, and Yang Zhongjian was appointed deputy director and director of the Beiping Branch.

When he first entered Shu Province, he found Emei Dragon in Rong County
In the 1930s, Yang Zhongjian's research direction began to shift to Chinese Mesozoic reptiles. During this time, he stumbled upon an article written by an American paleontologist in the University of California Geology Bulletin, which mentioned dinosaur fossils that had been transported back to the United States 20 years earlier from the Zigong region of Sichuan.
"These dinosaur fossils were found in China, so why should they be taken away by foreigners for study?"
Out of the feeling that the fossils were scattered overseas and his interest in the dinosaurs themselves, Yang Zhongjian came to the artesian well and Rong County area (belonging to Zigong City) in the middle of summer of 1936. There, Yang Zhongjian and others, together with experts from the United States, despite the heat of the Sichuan furnace, carefully searched within the scope of the dinosaur fossils found that year, but they did not find anything.
Unwilling to accept defeat, Yang Zhongjian resolutely expanded the search area, and finally found it in a small hill called Watermelon Mountain (see photo below), about 1.5 kilometers east of the county seat of Rong County. From July 2 to 16, Yang Zhongjian personally led assistants and migrant workers to overcome the double problems of sweltering heat and mosquito bites, and after half a month of struggle, finally successfully excavated a relatively complete dinosaur fossil. After research, Yang Zhongjian determined that the fossil belonged to a large sauropod dinosaur and named it Rongxian Emei Dragon.

In 1937, the July 7 Incident broke out, and Yang Zhongjian and others were forced to move to Kunming to continue their work, but Japanese bombers soon appeared here, and Yang Zhongjian and his assistants had to move again and set up a temporary work site in the old Guandi Temple in Wayao Village.
The harsh working conditions did not break Yang Zhongjian's belief, and he continued to study the fossils at hand while having new plans. The working point is located in the Lufeng Basin, the terrain of the basin is the easiest to retain fossils, Yang Zhongjian, who knows this, boldly speculated that there must be dinosaur fossils here, and then he inadvertently discovered that the oil lamps used by local farmers were made of substances similar to dinosaur spines. He added more confidence and was determined to "appear" the dinosaurs here.
After several days of unremitting efforts, Yang Zhongjian and others finally found in October 1938 in Dawa Village, Shawan Dahuangtian, located half a kilometer northeast of Lufeng County: a complete dinosaur skeleton was lying reclining in an excavation pit with its head facing outwards and its limbs facing inward. The discovery was so exciting to everyone that excavations began. Due to the sparse population of Shawan Village and the lack of accommodation conditions, the team members had to bring their own dry food every day, going back and forth between the excavation site and the work site, and after a month of excavation, a complete fossil of Lu Feng Dragon was finally completely seen.

After research, Yang Zhongjian will find that the dinosaur in front of him is between 4 and 5 meters long, with a long neck and a small and short head, thick limbs, short front legs and long hind legs, and small serrations on the edges of small teeth, through these features, Yang Zhongjian determined that the fossils in front of him belonged to the ancient foot suborder Plateosaurus under the order Lizard, and named it Xu Lufeng dragon according to the location of the fossil discovery and the name of one of his mentors when he was studying in Germany. Living in the early Jurassic Period 190 million years ago, Xu Lufenglong fed on the branches and leaves of plants, and was the first dinosaur to be independently searched, excavated and studied Chinese, and was known as the "First Dragon of China". For such a discovery, Yang Zhongjian was naturally extremely excited, and the creative inspiration was stimulated at once, so there was the poem at the beginning of the article.
After the victory of the War of Resistance Against Japan, Yang Zhongjian came to work at the Nanjing headquarters of the Geological Survey. In April 1949, the nationalist government, which had already lost its way, tried to lure him to work in Taiwan, and in the face of the generous conditions promised by the nationalist government, Yang Zhongjian, who had participated in the May Fourth Movement and had a deep personal relationship with Mao Zedong, flatly refused.

Mamen Creek Dragon, named when out of the "Oolong"
If you love museums or pay attention to museums around the world, you will find an interesting phenomenon: many museums around the world have the same unique appearance of dinosaurs: its neck is surprisingly long, almost half the length of the entire body, but its head is surprisingly small. It is Mamenxiosaurus, one of the largest sauropod dinosaurs found in China. This behemoth was also named by Academician Yang Zhongjian!

After the founding of New China, Yang Zhongjian returned to Beijing and served as the director of the research office of vertebrate paleontology (the predecessor of the Institute of Modern Research) of the Chinese Academy of Sciences, and the main research object was still dinosaurs. The most famous of these is the discovery of the Mamen Creek Dragon.
In 1952, near the Mamingxi Ferry in Yibin City, Sichuan Province, construction workers were busy in the heat, when suddenly, a worker accidentally found many bones-like stones while chiseling rocks, which finally fell into Yang Zhongjian's hands.
Yang Zhongjian, who received the fossil, immediately began to study, he found that the shape of the fossil in front of him was very similar to the four-legged sauropod dinosaur Thunder Dragon, but the length of the neck almost caught up with the torso, considering that the world had never found a dinosaur with a neck that accounted for such a long proportion of the whole body, Yang Zhongjian believed that this was a new dinosaur. He named it Mamingxi Dragon according to the place of discovery, and according to the international naming convention of genus name + species name, the earliest discovered model species was named Jianmingxi Dragon (taking the meaning of building the motherland), but I don't know if it is Professor Yang's accent problem, when he said the name he gave to the fossil in front of him, others all heard it as MamenXi Dragon, and this "oolong" has been preserved to this day.
The neck length of mamen creek dragon can exceed 14 meters! It has the largest neck-to-body ratio of any dinosaur ever discovered.

Dare to ask Fang Ling? Juniors please work harder
People familiar with Yang Zhongjian know that he has a habit: he likes to inquire about the age of students, and then encourages the other party to work harder in a mocking way and strive for early achievements. For example, in 1953, a young man named Qiu Zhonglang went to work at the research institute, Yang Zhongjian asked him about his age and grades, and when he got 26 years old and studied the two answers of anthropology, Yang Zhongjian pretended to be disappointed and said: "Many people are already famous at this age, but you have just started to study." ”
Although such ridicule has embarrassed many students, it has not affected the degree of respect of Yang Zhongjian, because the pioneer of Chinese vertebrate research has always attached importance to teaching students by example.
In 1975, when he heard the news of the abundance of dinosaur fossils in wujiaba and Dashanpu areas of Zigong City, Sichuan Province, he resolutely conducted a field investigation at the age of 78, and after arriving at the scene, he personally observed the nature of the rock formations and stratigraphic conditions of the fossil places, asked about related matters, and when it was confirmed that there may indeed be large-scale dinosaur fossils here, Yang Zhongjian, who had been faltering, thought of the situation of personally excavating the Emei Dragon in Rong County, and could not help but issue the feeling of "Sichuan dinosaurs are many, Zigong is a nest".

Four years later, in January 1979, Yang Zhongjian completed his 82-year journey in life, and according to his last wishes, his family buried him next to the Pekingese ruins on The Dragon Bone Mountain in Zhoukoudian, Beijing. In the same year, the dinosaur fossils of Dashanpu shocked the world, and Yang Zhongjian's sentence "There are many dinosaurs in Sichuan, Zigong is a nest" before his death has become the city slogan of Zigong.
2017 marks the 120th anniversary of the birth of Academician Yang Zhongjian. Han Qide, vice chairman of the National Committee of the Chinese People's Political Consultative Conference and chairman of the Central Committee of the Jiusan Society, commented: "Mr. Yang Zhongjian's life is a thick book. The patriotism, diligence and indifference in the "book" are all enlightening and inspiring future generations.
