Tian Shuyang was born in 1884, ranking the third in his family. 1905, under the influence of his eldest brother Tian Zhongyang, he was admitted to Nanjing Nanyang College of General Education. 1906, in response to the Pingyi uprising on the Hunan-Jiangxi border, the headquarters of the Tokyo League sent some members back to China to instigate the revolution along the Yangtze River. Sun Hebai plans to assassinate Duan Fang, the governor of Liangjiang, and hold an uprising. Tian Shuyang took the initiative to contact this matter. In February, 65438, Tian Shuyang moved to Anqing because the plan leaked. Soon, Tian Shuyang joined the Anqing New Army as the battalion commander. 1908, 1 1 In June, Tian Shuyang participated in the Mafaoying Uprising in Anqing. After the failure of the uprising, Tian Shuyang avoided Jiangxi and continued his revolutionary activities. 19110 After the Wuchang Uprising broke out in June, various provinces responded in succession. Tian Shuyang returned to Fengyang to organize the Jianghuai Rebel Army under the command of the Allied Forces. 1 1 June, 2008, joined forces with Huai Shang Army who attacked Fengyang and occupied Fengyang. Since then, Tian Shuyang has served as the head of Huaishang Military Camp.
Fengyang is a battleground for military strategists in past dynasties. Zhang Xun, governor of the two rivers in the Qing Dynasty, heard that Fengyang was occupied and was afraid that the back road would be cut off. On June165438+1October 14, he invaded Fengyang Linhuai Pass. After Tian Shuyang inquired, he led the troops to battle with reinforcements for two days and nights, wiped out the invading enemy and saved Linhuai Pass. 65438+ February, Jiangsu and Zhejiang allied forces captured Nanjing, and Zhang Xun led the remnants to flee northward along Jinpu Road. Tian Shuyang led the Huai Shang Rebel Army to stop the Qing army in Nangang, Linhuai Pass. After fighting, the rebels ran out of ammunition, and Tian Shuyang died heroically in the battle at the age of 27.
Tian Jiyang was born in 1890, with the word Angfu, ranking fourth. 1906, Tian Jiyang went to Anqing at the call of his eldest brother Tian Zhongyang and was admitted to Anhui Army Surveying and Mapping School. Under the recommendation of Tian Zhongyang, he joined the Yue King Association and the League. In September, Tian Jiyang was selected to study in the Cavalry Training College. 1at the beginning of 907, Tian Jiyang came to Anqing from Nanjing and soon served as the new army battalion. In April of the same year, Tian Jiyang was selected into the new army horse camp with excellent graduation examination results. After he took office, he often met with revolutionaries Xiong and Fan Chuanjia from Ma camp and artillery camp to discuss anti-Qing issues and contacted hundreds of people to join the meeting. 1June, 907, after Xu Xilin failed in the Anqing uprising, Tian was furious and vowed: "Kill yourself and be a man, and respect your ambition!" 1908165438+10, Tian Jiyang participated in and led the mafoying uprising in Anqing, and was praised as "the dust after Xu Gong, the first voice in Wuchang".
1908165438+1October 14 and 15, Emperor Guangxu and Empress Dowager Cixi died one after another. Xiong, Fan Chuanjia and Tian Jiyang think this is an excellent opportunity for the uprising. 1 191On the afternoon of October 30th, Xiong et al. 10 held a secret meeting in the Yip's Guild Hall in Anqing, and finally drew up thirteen operational secrets. At 9 o'clock that night, Tian Jiyang arranged an uprising. 10 sharp, Maying and Artillery Battalion officers and men took the ignition as the signal, 1 0, and more than 1,000 people fought out of Anqing City. However, due to the early preparedness of the Qing army, the insurgents in the city could not meet, and the insurgents outside the city struggled day and night, unable to attack the city and were besieged by the Qing army. The insurgents had to retreat in the direction of Luzhou. Tian Jiyang returned to Fengyang after his breakthrough. After learning about it, the Qing army went to Fengyang to arrest it. 165438+1On October 27th, Tian Jiyang was arrested and died heroically soon at the age of 18.
In order to commend the Tian brothers, in 19 12, the governor of Anhui Province wrote to President Sun Yat-sen for approval, posthumously awarded Tian Jiyang as an army general and Tian Shuyang as an army lieutenant general, and established Tian Shuanglie Temple and Martyrs Temple in Fengyang City. The epitaph reads: "The soul of China, the blood of the righteous, the glory of Huai River in Hu Aishan, the precious blood of the plain". 1984, with the approval of Anhui provincial people's government, Tian Shuang's tomb was moved to Fengyang Revolutionary Martyrs Cemetery for future generations to pay tribute to.
Li Siguang was born in a rural teacher's family in Xiazhangjiawan Village, huilong town, Huanggang County, Hubei Province. When I was a child, I went to the village with my father to read the "Four Books" and "Five Classics" and learn to write poetry. He is studious and loves his work. Because he often listened to his father's stories about the Sino-Japanese War of 1894-1895, China's fiasco and the corruption and incompetence of the Qing government, Li Siguang was full of patriotic enthusiasm when he was young. He made up his mind to live up to his motherland, learn to build ships and defeat imperialist aggression when he grew up. 1902, a new school opened in Hunan and Hubei. Li Siguang left home and went to Wuhan, the provincial capital, and was successfully admitted to West Road High School. Because he was among the best in every exam, he didn't study for two years and didn't graduate, so he was selected by Hubei Province to study in Japan. 1July, 904, Li Siguang arrived in Tokyo to study Japanese at Hongwen College.
Sun Yat-sen personally led the League to join the China League.
1In August, 905, Li Siguang joined the China Alliance led by Dr. Sun Yat-sen himself, becoming the youngest member among the first members. Seeing his youth, Dr. Sun Yat-sen encouraged him to "study hard and serve the country", which strengthened Li Siguang's determination to study hard and serve China. 1907 In July, Li Siguang was admitted to Osaka Higher Institute of Technology to study shipbuilding machinery, and his desire to learn shipbuilding for the motherland was initially realized. 19 10 in July, Li Siguang graduated and returned to China as a teacher and director of Wuchang Hubei secondary technical school. At the turn of autumn and winter in the following year, he took part in the sixth imperial examination for returned overseas students held by the Qing government, with excellent results, and was awarded the title of "Top Scholar in Engineering". In June of the same year, 65438+ 10/0, Wuchang Uprising was successful and the Qing government was overthrown. Wuchang established the Hubei Army Dudufu, and Li Siguang first served as the financial counselor of Dudufu, and was later elected as the Minister of Industry of Hubei Province. 19 12 June, changed to director of the industry department. Soon, Yuan Shikai stole power and usurped the fruits of the revolution, and the Revolution of 1911 failed. Li Siguang, who was depressed, angrily resigned as the director of the Industry Department. 1965438+In July, 2003, Li Siguang was informed by the Provisional Memorial Bureau that he was recommended to study in Britain and enter Birmingham University at official expense. Considering that shipbuilding for the motherland is inseparable from steel, if steel is to be made, it must be smelted first. So he studied mining for a year first, and felt that mining could not be separated from geology. He decided to transfer to the Department of Science Geology, began to specialize in geology, and then embarked on the road of "saving the country through science".
1On July 7, 937, the Lugouqiao Incident broke out. Before and after the incident, Chiang Kai-shek and Wang Jingwei invited professors from various universities and leaders from all walks of life to talk in Lushan, saying that they exchanged views on political, economic and educational issues. Li Siguang came to Lushan as the first invitee. Li Siguang also wanted to know the attitude of the National Government towards the War of Resistance. So after going up the mountain, he first visited Wang Jingwei, who had contacts with him in Japan and South Kyoto. As soon as they met, Li Siguang put forward the view that "if you don't fight now, there will be no way out", while Wang Jingwei talked about the reasons why you can't fight, which made Li Siguang very disappointed. When Chiang Kai-shek and Wang Jingwei formally held talks, Li Siguang flatly refused their invitation.
Because Li Siguang didn't buy Chiang Kai-shek's account, and he always opposed Chiang Kai-shek, when the news came that Chiang Kai-shek wanted to arrest him, the Li Siguang family moved to the countryside for the safety of their families. The quiet environment in the countryside made Li Siguang calm down and engage in scientific research. Under the kerosene lamp, he completed the first drafts of papers and works such as Review of Twenty Years' Experience and Experimental and Theoretical Research on Mountain Structure. Although living conditions were very difficult, he never stopped his scientific research. 194 1, Li Siguang won the "Mr. Ding Wenjiang Memorial Fund Committee" award.
With the return of the National Government to Nanjing, the Institute of Geology moved back to Nanjing. 1946165438+1October, Li Siguang took a boat from Chongqing to Nanjing. At this time, the civil war provoked by the Kuomintang had been fought for half a year, which made him completely desperate for Chiang Kai-shek. In Nanjing, although Zhu Jiahua, President of Academia Sinica, greeted him at the dock, Li Siguang did not disembark and went to Shanghai directly. 1948 In February, Li Siguang was invited to attend the18th annual international geological conference held in London, but did not return to China immediately, but moved overseas temporarily. With the further development of the situation in the war of liberation in favor of the people, important officials of the national government began to flee to the south, and the Institute of Geology in Nanjing was also told to move to Zhongshan University in Guangzhou. After learning this news, Li Siguang, who is abroad, kept writing letters to colleagues in the Institute of Geology, hoping that colleagues would try to prevent the Institute from moving south. Due to the strong opposition of Li Siguang and the joint efforts of other colleagues in the Institute, the Institute finally stayed in Nanjing and returned to the people's arms almost intact after liberation.
1949 At the beginning of April, the China delegation led by Guo Moruo went to Prague to attend the World Peacekeeping Conference. Before going abroad, Zhou Enlai instructed Guo Moruo to contact Li Siguang, who was still abroad, and invited him to return to China to participate in the construction of new China. Guo Moruo wrote a letter to Li Siguang as instructed, asking him to return home. A few days after the liberation of Nanking, when Commander Chen Yi visited the Institute of Geology, he asked about Li Siguang and told the scientists of the Institute clearly that Li Siguang was welcome to return to China.
While Li Siguang was anxiously waiting for his departure, the Kuomintang authorities who fled to Taiwan Province Province plotted to prevent Li Siguang from returning home. They want Li Siguang to make a public statement and refuse to accept the position of CPPCC member under the leadership of the * * * production party. If you don't do it, detain him Li Siguang decided to leave England. Li Siguang had already arrived in France when the Kuomintang Embassy sent someone to look for him. 1April 6, 950, Li Siguang returned home safely with his family. He accepted the arrangement of Zhou Enlai and became the vice president of China Academy of Sciences.
Li Siguang challenges the theory of "China is poor in oil"
There were three national geological institutions in old China: Central Geological Survey, Institute of Geology of Academia Sinica and Bureau of Mineral Exploration. Through investigation and seeking the opinions of geologists, the New China Government Council approved the establishment of a scheme of "one meeting, two institutes and one bureau": one meeting, that is, the geological work plan allocation Committee, and later changed to the geological work steering Committee; Two, namely Institute of Geology of Chinese Academy of Sciences and Institute of Paleontology; The first bureau is the Bureau of Mineral Geological Exploration of the Financial and Economic Committee.
After the national geologists were organized, a new situation appeared in China's geological work and geological research. With the further development of economic construction, the Central People's Government decided to set up the Ministry of Geology at its17th meeting, and appointed Li Siguang as the minister in August 1952. Since then, Li Siguang has stepped onto an important post leading the national geological work.
Before Li Siguang became the minister of geology, the so-called foreign geological authorities, based on their superficial research on China, came to the conclusion that it is unlikely to find oil in the southeast of China; The possibility of finding oil in the southwest is more distant; Northwest China will not become an important oil field; There won't be much oil in the northeast. In a word, China is an oil-poor country. This conclusion was believed by the whole geological community in China at that time, but Li Siguang disagreed.
As early as 1928, Li Siguang challenged the conclusion that "China is poor in oil" according to his own research. 1935, he once again suggested that China might find oil. However, it is not easy to overturn the authoritative conclusion. After the founding of New China, the economic construction has developed rapidly, and the demand for oil is increasing. Oil production has become a serious bottleneck restricting the economic construction of New China. President Mao Zedong personally called Li Siguang to Zhongnanhai and asked with great concern, "Some people say that China is poor in oil. What do you think of this problem? If China is really short of oil, should it take the road of synthetic oil? To build a new China, oil is indispensable. It flies in the sky and runs underground. It can't move without oil. "
Li Siguang fully understood the weight of the Chairman's remarks. He wants to share his worries for the leader, and the trust of the leader has become the driving force of his unremitting efforts. Li Siguang has always disagreed with "China's theory of being poor in oil". When he made a report in the General Administration of Petroleum, he pointed out with his finger that there are three areas with the greatest prospects for oil exploration in China: first, the Yunnan-Myanmar geosyncline in Tibet and Xinjiang; The second is the northern Shaanxi basin of Alashan; Third, the Northeast Plain and the North China Plain.
Li Siguang's report is inspiring. On the basis of detailed analysis of the geological structure characteristics of these three oil-bearing prospect areas, he clearly pointed out that Qaidam Basin, Heihe area, Sichuan Basin, Yishan platform, North China Plain and Northeast Plain should be the key areas for oil exploration. 1in March, 1956, he served as the director of the State Petroleum Geology Committee. Under his guidance, the national oil survey began. Through the general survey, oil-bearing prospective areas have been discovered all over the country.
According to Li Siguang's theory, China's oil army entered the Songliao Plain and started the Daqing oil battle. Facts have proved that Li Siguang's analysis is scientific. 1960 is the most difficult year in new China. However, in this year, the battle of Daqing Oilfield won a great victory. From the late 1950s to the 1960s, the exploration departments successively discovered Daqing Oilfield, Dagang Oilfield, Shengli Oilfield and Huabei Oilfield. When the national construction is in urgent need of a lot of energy, because of the hard work of geologists, rolling oil appeared, which not only removed the label of "China is poor in oil", but also gave the most powerful proof of Li Siguang's original geomechanics theory.
1964 65438+On February 20th, the Third National People's Congress opened in Beijing. As a representative of the people, Li Siguang attended the grand meeting. During the meeting, President Mao Zedong personally received him. As soon as they met, Chairman Mao said to him kindly and humorously, "Li Lao, you played well in Tai Ji Chuan!" Li Siguang, who is practicing Tai Ji Chuan, really thought that Mao Zedong asked him about playing Tai Ji Chuan, so he quickly explained: "I had an operation a few years ago and my health was not very good. I studied Tai Ji Chuan in Hangzhou for a while, but I didn't play well. " In fact, Mao Zedong's attack on Taiji Chuan refers to finding oil, which is a full affirmation of Li Siguang's contribution to finding oil for China.
At the Third National People's Congress, Zhou Enlai pointed out in the government work report: "The Daqing Oilfield, which was planned to be built in the first five-year plan, was discovered on the basis of the original petroleum geological theory of China geologists." Hearing this, Li Siguang, who attended the meeting, could not help shedding tears of excitement.
"At present, the most urgent needs are' oil' and' uranium' mines."
In a country where the people are the masters of their own affairs, Li Siguang is young and proud, feels stiff and confident, and has a deeper understanding of China's * * * production party. He said: "For a century, especially in recent decades, after the emergence of the * * * production party in China's political history, the people of China found the correct leadership, got rid of the humiliating and oppressed life, and stood up in front of the world."
1958 12 according to Li Siguang's application and performance, He Changgong and Zhang Jinfu introduced him to join the producer party of China. Since then, Li Siguang has changed from a national democrat to a fighter. At that moment, the old scientist who had gone through two eras and a bumpy journey was intoxicated, and he felt great happiness embracing him. Li Siguang, who was nearly seventy years old at that time, said that he was "like a newborn baby, and a new starting point in life has just begun". He seems to be full of infinite strength and devoted himself to the upsurge of socialist construction with vigorous energy.
When it comes to the nuclear industry in New China, many people can name a list of scientists, but without Li Siguang, the list is at least incomplete. Li Siguang proposed "atomic fission" as one of natural gas energy sources in the early 1920s. He believes that uranium deposit is a rare radioactive deposit, which often appears in areas with complex geological structure. In 1930s, he sent students to Guangxi to inspect uranium deposits, and discovered phosphate uranium deposits, fatty lead uranium deposits and pitchblende for the first time. This work was later interrupted because the actual utilization schedule could not be mentioned for the time being because of the war.
/kloc-in the summer of 0/953, Li Siguang went to Beidaihe for recuperation, and Zhu De and Li Fuchun were also there. Li Siguang usually has the habit of observing geology when walking. One day, on the beach in Beidaihe, he found a pile of black sand while walking. Local fishermen told him that they dug a lot of this black sand during the Japanese occupation. That night, Li Siguang wrote to Beijing, asking Qian Sanqiang to borrow the instrument for testing, and immediately reported the matter to Zhu De. Zhu De suggested that the investigation of radioactive mineral resources should be started as soon as possible.
In the following year, Li Siguang set up a second office in the General Survey Committee of the Ministry of Geology, which was responsible for the investigation of uranium resources, which was equivalent to continuing the work he wanted to do 20 years ago but failed to carry out. At the 29th annual meeting of the Geological Society, he pointedly pointed out: "At present, the most urgent needs are' oil' and' uranium' mines."
195565438+ 10/5. President Mao Zedong personally presided over the enlarged meeting of the Central Secretariat and listened to reports from Li Siguang, Liu Jie and Qian Sanqiang. Chairman Mao asked Li Siguang at the meeting: "Does China have uranium ore for atomic bombs?"
Li Siguang took out a sample of uranium ore he had with him and replied, "Yes. The general natural uranium ore can only be used as a few thousandths of atomic bomb raw materials, so it needs a lot of uranium resources and uranium enrichment plants. " Li Siguang and others surveyed ore samples on the spot in front of the central leadership. As soon as the detector approached the ore, it produced a signal.
Chairman Mao was very happy to see this. He said, "Our country now knows that there are uranium mines. Further exploration is sure to find more uranium deposits. There are many other things in recent years, and it is too late to catch this thing. Now is the time, it's time to catch. As long as we have manpower and resources, any miracle can be created. "
Since then, Li Siguang has been at the core of leading China's nuclear industry. He used to be the deputy director (director Chen Yun) of the National Atomic Energy Commission established in 1956 and the director of the Nuclear Science Committee of China Academy of Sciences established in 1958. He not only directly leads the routine work of the Nuclear Science Committee, but also personally explains and deploys to geologists from the grassroots. Among the three east-west structural zones proposed by him, uranium deposits with rich reserves and high grade have been discovered one after another.
19641June16th, China's first atomic bomb exploded successfully. Li Siguang's contribution is not difficult to infer.
Concentrate on earthquake research in his later years.
After returning home, Li Siguang once settled in Xiangbizou near Xiangshan. In the 1960s, in Dongdan, the city where Li lived, he was invited to see the house. He felt that the house was too luxurious and violated his usual interest in life, so he gave it up. Since then, he personally selected the site for design, and the country built a small building in the north of Zizhuyuan. This is a two-story building with a total construction area of 989. 1 m2, surrounded by courtyard walls, with the courtyard doors facing north and the building doors facing west. There are winding paths in the courtyard, including rockeries, fountains and fruit trees.
Li Siguang, a geologist, must touch "water and soil" when he chooses his residence, just like his ancestor, and so does this place. Judging from the surrounding historical sites, it can be regarded as a "land of feng shui": there is a thousand-year-old ginkgo tree in front of the door. According to the measurement, the trunk circumference is 9.8m, the height of the tree is about 27m, and the shaded area of the crown is about 400 m2. Legend has it that when Li Zicheng attacked Beijing, he tied a horse to this tree. To the south of Lizhai is Zizhuyuan, to the west is Manjuki, and to the north is Huokeji. There are also several tombs of famous people in the past dynasties nearby, such as Gan Wen, the minister of war in Kangxi period of Qing Dynasty, and Liu Jin, the great eunuch of Ming Dynasty.
Li Siguang moved there from 1962 and lived there until his death in 197 1. He lives, works and studies here. Some small meetings chaired or attended by him are often held at home. The heads of geological departments such as He Changgong and Liu Jingfan often come home to report things, so the stateroom on the right hand side of the gate actually has the function of a conference room. There are bookcases and sofas around, and a long table and some chairs in the middle. On one side of the window, there are many geological samples of the fourth-season glacier sediments, most of which are the harvest of Li Siguang's field investigation.
Next to the living room is the office, and there is a glass blackboard at one end of the wall. When the geological team returns from field work and reports to Li Siguang, they often use this blackboard to explain or decorate, and also borrow this blackboard to teach geomechanics to scientific and technical personnel, which is probably a habit formed in his teaching career for many years.
China is a country with frequent earthquakes. Li Siguang attaches great importance to earthquake geology and earthquake prediction. As early as 1953, when the China Academy of Sciences established the Earthquake Working Committee, he personally served as the chairman. 1on March 8, 966, an earthquake of magnitude 7 or above occurred in Xingtai, Hebei province. The disaster area affects the hearts of the party and state leaders. Premier Zhou held many meetings to discuss relevant issues, and Li Siguang attended them. According to his own research results, Li Siguang put forward his insights, providing reference for the decision-making of the CPC Central Committee.
Strongly encouraged by the Prime Minister's two visits to Xingtai, Li Siguang also visited Xingtai and obtained important first-hand information. Li Siguang pointed out that the main task of seismic geological work is to detect the hiding places of underground "enemies" and monitor their activities, so as to ensure the safety of people's lives and property and serve the safety of socialist construction.
1968, it is widely rumored that there will be a strong earthquake in Beijing. Late one night, Li Siguang was informed of an emergency meeting in the State Council. When he arrived at the conference hall, it was already past two in the morning. Premier Zhou invited Li Siguang to sit next to him. The meeting was to study the report that the State Council received that an earthquake of magnitude 7 would occur in Beijing at 7: 00 that morning, and asked the State Council for approval to inform residents to move outdoors immediately. Matters, the prime minister invited Li Siguang, just want to listen to Li Siguang's opinion.
Li Siguang listened carefully to the reports from relevant parties, and called some observation stations in Beijing to ask if there were any abnormal phenomena. There is no abnormality in the answers from various places. At this time, Li Siguang told the Prime Minister that according to the long-term observation of in-situ stress in Xingtai and other areas, there was a major earthquake and generally there would be changes. According to the observation results of various observation stations in Beijing, there is no need to issue an alarm tonight, but of course we should pay close attention.
Premier Zhou felt that Li Siguang's analysis was very reasonable, so he agreed with Li Siguang's opinion and didn't sound the alarm that night. Facts have proved that Li Siguang's judgment is correct, and Beijing has avoided an unnecessary action.
Li Siguang's scientific research achievements have played an important role in the decision-making of the CPC Central Committee and attracted the attention of President Mao Zedong. 1969 One day in May, Li Siguang was asked by Chairman Mao to talk. They talked about the origin of life from the origin of celestial bodies. When leaving, the chairman said to Li Siguang, I really want to read your book. Can you send me some books? He asked Li Siguang to help collect some scientific information at home and abroad.
Li Siguang asked, "What kind of scientific materials do you want to see?"
Chairman Mao drew a big circle with his hand and said, "It is the information of your research scope."
Li Siguang was very moved and thought it was Chairman Mao's concern for science. So, Li Siguang personally selected seven scientific materials and gave them to Chairman Mao and other leaders.
Li Siguang, First Vice President and Academician of China Academy of Sciences (formerly a member of the Faculty), Chairman of the National Federation of Science and Technology, First Chairman of the China Association for Science and Technology, Vice Chairman of the World Association of Scientists, and Second, Third and Fourth Vice Chairmen of the Chinese People's Political Consultative Conference. He is a versatile scientist. He writes well not only prose, but also old-style poems. Even geological papers are "colorful" His musical attainments are also quite profound, especially the violin. 1920, in Paris, he used a piece of 8 pieces of paper, 12 lines, and composed the violin "It's hard to walk", which was the first violin piece composed by China people, with a deep theme and a high-pitched strong sound. Nearly 80 years later, this violin piece was first played in public at the centenary party of Peking University. Its appearance corrected the statement that Ma Sicong was the earliest violin composer in China.
Li Siguang treats people kindly, kindly, and doesn't put on airs. He treats his subordinates, the staff around him and the nanny equally. So, if you have any different opinions, you are willing to raise them to his face and have no scruples. But that doesn't mean that he wants everyone to go, just that there is no need to train people. This also reflects the mind and self-restraint of a great scientist.
Li Siguang still paid great attention to earthquake research in his later years. He often analyzed a large number of observation data and made many in-depth field visits to earthquake precursors at the risk of aneurysm rupture. One day before his death, he said to the doctor earnestly, "Give me another half a year, and the exploration of earthquake prediction will be effective." At the last moment of his life, he left a will for his children, talking about earthquake prediction, geothermal utilization, marine geology and other issues that he often thought about in the last few years. He devoted all his life's efforts to the great motherland and people!
1971On April 29th, Li Siguang died of illness at the age of 82. Premier Zhou Enlai read out his will in tears at the memorial service in Li Siguang, and all the audience were moved. At the end of the memorial service, Premier Zhou instructed the staff around Li Siguang to sort out Li Siguang's works and inherit Li Siguang's scientific spirit.
