Who are the heroes of the Revolution of 1911?

Tian Shuyang and Tian Jiyang, the twin brothers of the Tian family, are natives of Fucheng Town, Fengyang County, Anhui Province. During the Revolution of 1911, they fought bravely to save the country and the people, one after another.

Tian Shuyang was born in 1884, named Yahao, and was the third eldest child in the family. In 1905, under the influence of his eldest brother Tian Zhongyang, he was admitted to the Nanyang General Bentan School in Nanjing. In 1906, in response to the Pingliu Li Uprising on the border between Hunan and Jiangxi, the Tokyo Tongmenghui headquarters sent some members back to China to instigate a revolution along the Yangtze River. Sun Yujun, Bai Wenwei and others planned to assassinate Duan Fang, the governor of Liangjiang, and staged an uprising. Tian Shuyang worked actively to contact the matter. In December, because the plan was leaked, Tian Shuyang came to Anqing. Soon, Tian Shuyang joined the Anqing New Army and served as the commander of the infantry battalion. In November 1908, Tian Shuyang participated in the Anqing Horse Artillery Battalion Uprising. After the uprising failed, Tian Shuyang avoided Jiangxi and continued his revolutionary activities. After the Wuchang Uprising broke out in October 1911, all provinces responded one after another. Tian Shuyang was ordered by the Tongmenghui to return to Fengyang to organize the Jianghuai Rebel Army. In November, she cooperated with the Huaishang Army who attacked Fengyang and occupied Fengyang. After that, Tian Shuyang served as the battalion commander of the Huaishang Army.

Fengyang is a battleground for military strategists of all ages. After Zhang Xun, the governor of Liangjiang in the Qing Dynasty, heard that Fengyang was occupied, he was afraid that his retreat would be cut off, so he invaded Linhuai Pass in Fengyang on November 14. After Tian Shuyang inquired, he led his troops to fight and fought fiercely with the reinforcements for two days and nights. They completely wiped out the invading enemies and saved Linhuai Pass. In December, the Jiangsu-Zhejiang coalition forces captured Nanjing, and Zhang Xun led the remaining troops to flee north along Jinpu Road. Tian Shuyang led the Huaishang Rebel Army to block the Qing army at Nangang of Linhuaiguan Pass. After a fierce battle, the rebel army ran out of ammunition and food. Tian Shuyang died heroically in the battle at the age of 27.

Tian Jiyang was born in 1890, named Angfu, and ranked fourth. In 1906, Tian Jiyang went to Anqing at the call of his eldest brother Tian Zhongyang and was admitted to the Anhui Army Surveying and Mapping School. Under the recommendation of Tian Zhongyang, he successively joined the Yuewanghui and the Tongmenghui. In September, Tian Jiyang was selected to study at the Cavalry Training Center. In early 1907, Tian Jiyang came to Anqing from Nanjing and soon became the commander of the New Army's Infantry Battalion. In April of the same year, Tian Jiyang was selected to serve as the commander of the New Army's cavalry battalion due to his excellent grades in the graduation examination. After he took office, he often met with Xiong Chengji, Fan Chuanjia and other revolutionaries who were also active in Maying and Paoying to discuss major anti-Qing affairs, and contacted hundreds of people to join the Yuewanghui. In June 1907, after Xu Xilin's uprising failed in Anqing, Tian Jiyang angrily swore: "I will kill myself to be a benevolent person, in order to respect Boxun's ambition!" In November 1908, Tian Jiyang participated in leading the uprising known as "Following the footsteps of Xu Gong, starting from The Anqing Horse Artillery Battalion Uprising was the forerunner of Wuchang.

On November 14 and 15, 1908, Emperor Guangxu and Empress Dowager Cixi died successively. Xiong Chengji, Fan Chuanjia, Tian Jiyang and others believed that this was an excellent opportunity for an uprising. On the afternoon of November 19, Xiong Chengji and more than 10 people held a secret meeting at the Ye Family Hall in Anqing, and finally formulated thirteen secret combat orders. At about nine o'clock that night, Tian Jiyang made arrangements for the uprising. At ten o'clock, the officers and soldiers of the horse camp and artillery camp used the signal to light a fire, and more than 1,000 people attacked Anqing City. However, because the Qing army had already prepared for it, the insurgents inside the city were unable to respond. The insurgents outside the city fought hard all day and night, unable to attack the city, and were besieged by the Qing army. The rebel army had to retreat towards Luzhou. After Tian Jiyang broke through the encirclement, he returned to Fengyang. After the Qing army learned about it, they went to Fengyang to arrest him. On November 27, Tian Jiyang was arrested and soon died heroically at the age of 18.

In order to commend the Tian brothers, in 1912, Anhui Governor Bai Wenwei petitioned President Sun Yat-sen for approval, posthumously conferring Tian Jiyang the rank of Army General and Tian Shuyang the rank of Army Lieutenant General, and established the Tian Temple in Fengyang City. The Shuanglie Temple and the Dahan Zhonglie Temple. The epitaph reads: "The soul of China, the blood of martyrs, the Huaishan Mountains and the Huaihe River are brighter, and the plains are filled with your blood." In 1984, with the approval of the Anhui Provincial People's Government, the tombs of Tian's twin martyrs were moved to Fengyang Revolutionary Martyrs Cemetery for future generations to pay their respects.

Li Siguang was born into a family of rural teachers in Xia Zhangjiawan Village, Huilong Town, Huanggang County, Hubei Province. When he was a child, he went to a village school with his father to read the "Four Books" and "Five Classics" and learn to write poetry. He is diligent, studious and loves to work.

Because he often heard his father tell stories about China's disastrous defeat in the Sino-Japanese Sino-Japanese War and the corrupt and incompetent Qing government that humiliated the country, Li Siguang was full of patriotic enthusiasm at a young age and secretly determined that when he grew up, he must strive for the motherland and learn to build ships. , Defeat imperialist aggression. In 1902, new schools were opened in Lianghu. Li Siguang left his home and came to Wuhan, the provincial capital, and was successfully admitted to the West Road Higher Primary School. Because he ranked among the best in every exam, he was selected by Hubei Province to study in Japan at official expense before he graduated for less than two years. In July 1904, Li Siguang arrived in Tokyo and entered Hongwen Academy to study Japanese.

Sun Yat-sen personally led the alliance to join the China Tongmenghui

In August 1905, Li Siguang joined the China Tongmenghui under the leadership of Sun Yat-sen himself, becoming the youngest member among the first batch of members. Seeing his young age, Mr. Sun Yat-sen encouraged him to "work hard to learn and serve the country", which further strengthened Li Siguang's determination to study hard and serve China. In July 1907, Li Siguang was admitted to the Marine Machinery Department of Osaka Technical High School to study shipbuilding machinery, which initially fulfilled his wish to learn shipbuilding for his motherland. In July 1910, Li Siguang returned to China after graduation and served as teacher and factory director of Wuchang Hubei Secondary Industrial School. At the turn of the autumn and summer of the next year, he participated in the sixth court examination held by the Qing government for overseas students returning to China, with excellent results, and was awarded the title of "Jinshi in Engineering". On October 10 of the same year, the Wuchang Uprising was successful, the Qing government was overthrown, and the Hubei Army Governor's Office was established in Wuchang. Li Siguang first served as counselor of the Financial Management Department of the Governor's Office, and was later elected as Minister of Industry of Hubei Province. In 1912, he was changed to Director of the Industrial Department. Soon, Yuan Shikai stole power and usurped the fruits of the revolution, and the Revolution of 1911 failed. With a depressed mood, Li Siguang angrily resigned from his position as director of the Industrial Department. In July 1913, Li Siguang was notified by the Provisional Inspection Bureau that he would be sent to study in England at official expense and enter the University of Birmingham. Considering that building ships for the motherland cannot be without steel, and if you want steel, you must first engage in smelting, so he first studied mining for a year, and felt that mining was inseparable from geology. He decided to transfer to the Department of Science and Geology, and began to specialize in geology. embarked on the path of "saving the nation through science".

On July 7, 1937, the Marco Polo Bridge Incident broke out. Before and after the incident, Chiang Kai-shek and Wang Jingwei successively invited professors from universities across the country and leaders from all walks of life to hold talks in Lushan to exchange opinions on politics, economics, education and other aspects. Li Siguang came to Lushan as the first batch of invitees. Li Siguang also wanted to understand the Nationalist Government's attitude towards the war, so after going up the mountain, he first visited Wang Jingwei, who had had contacts with him in Japan and Nanjing. As soon as they met, Li Siguang put forward the view that "if we don't fight now, there is no way out", but Wang Jingwei talked about the reason why we can't fight, which made Li Siguang very disappointed. When Chiang Kai-shek and Wang Jingwei formally held a talk meeting, Li Siguang flatly rejected their invitation.

Because Li Siguang did not buy Chiang Kai-shek's blame, and he had always been anti-Chiang, when the news came that Chiang Kai-shek wanted to arrest him, Li Siguang's family moved to the countryside for the safety of his family. The quiet environment in the countryside allowed Li Siguang to calm down and engage in scientific research. Under the kerosene lamp, he completed the first drafts of papers and books such as "Review of Twenty Years of Experience" and "Experimental and Theoretical Research on Mountain-shaped Structure". Despite the difficult living conditions, he never stopped his scientific research. In 1941, Li Siguang received the "Mr. Ding Wenjiang Memorial Fund Committee" bonus.

As the Nationalist Government returned its capital to Nanjing, the Institute of Geology also moved back to Nanjing. In November 1946, Li Siguang took a boat from Chongqing to return to Nanjing. At this time, the civil war provoked by the Kuomintang had already started for half a year, making him completely despairing of Chiang Kai-shek. When he arrived in Nanjing, although Zhu Jiahua, president of Academia Sinica, greeted him at the pier, Li Siguang did not get off the ship and went directly to Shanghai. In February 1948, after Li Siguang was invited to attend the 18th International Geological Annual Conference in London, he did not return to China immediately and temporarily moved overseas. As the situation of the Liberation War further developed in a direction favorable to the people, important officials of the Nationalist Government began to flee south one after another, and the Institute of Geology in Nanjing was also notified to move to Sun Yat-sen University in Guangzhou. After Li Siguang, who was abroad, learned the news, he wrote consecutive letters to his colleagues at the Institute of Geology, hoping that his colleagues would try to prevent the Institute of Geology from moving south.

Due to Li Siguang's strong opposition and the concerted efforts of other colleagues in the institute, the institute finally stayed in Nanjing and returned to the embrace of the people almost intact after liberation.

In early April 1949, a Chinese delegation headed by Guo Moruo went to Prague to attend the World Peace Conference. Before leaving the country, Zhou Enlai instructed Guo Moruo to contact Li Siguang, who was still abroad, and invite him to return to China to participate in the construction of New China. Guo Moruo complied and wrote a letter to Li Siguang asking him to return to China. A few days after the liberation of Nanjing, Commander Chen Yi visited the Institute of Geology. After asking about Li Siguang's situation, he clearly told the scientists at the Institute of Geology 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 hatched a conspiracy to prevent Li Siguang from returning to China. They wanted Li Siguang to make a public statement refusing to accept the position of member of the National Committee of the Chinese People's Political Consultative Conference under the leadership of the Communist Party. If he fails to do so, he will be detained. Li Siguang made a decisive decision and left the UK. When the Kuomintang embassy in the UK sent personnel to find Li Siguang, he had already arrived in France. On April 6, 1950, Li Siguang and his family returned to China safely. He accepted Zhou Enlai's arrangement and served as vice president of the Chinese Academy of Sciences.

Li Siguang challenges the theory that "China is poor in oil"

Old China had three national geological institutions: the Central Geological Survey, the Institute of Geology of Academia Sinica, and the Mineral Surveying and Surveying Department . After investigating and soliciting opinions from geologists, the Government Affairs Council of New China approved the plan to establish "one conference, two institutes, and one bureau": the first conference, namely the Geological Work Planning and Allocation Committee, later changed to the Geological Work Steering Committee; the second institute, namely Institute of Geology and Institute of Paleontology, Chinese Academy of Sciences; Bureau One, the Bureau of Mineral and Geological Exploration of the Financial and Economic Commission.

After geologists across the country were organized, a new situation emerged in my country’s geological work and geological research. With the further development of the economic construction situation, on August 10, 1952, the 17th meeting of the Central People's Government decided to establish the Ministry of Geology and appointed Li Siguang as the minister. Since then, Li Siguang has taken an important position in leading the national geological work.

Before Li Siguang became the Minister of Geology, foreign so-called geological authorities came to the conclusion based on their superficial research on China: It is unlikely to find oil in southeastern China; The possibility of oil is even more remote; the northwest will not become an important oil field; the northeast will not have a lot of oil. In short, China is an oil-poor country. This conclusion was believed by the entire Chinese geological community at that time, except Li Siguang who objected to it.

As early as 1928, Li Siguang challenged the conclusion that "China is poor in oil" based on his own research. In 1935, he again proposed that China might find oil. However, it is not easy to overturn the authoritative conclusion. After the founding of New China, economic construction developed rapidly and the demand for oil increased. Oil production has become a serious bottleneck restricting the economic construction of New China. Chairman Mao Zedong once personally called Li Siguang to Zhongnanhai and asked very worriedly: "Some people say that "China is poor in oil." What do you think of this problem? If China is really poor in oil, should we take the road of synthetic oil? New China To carry out construction, oil is indispensable. What flies in the sky and runs underground cannot move without oil."

Li Siguang understood the weight of the chairman's words very well. He wanted to share the worries of the leader, and the leader. His trust has become his unremitting motivation to move forward. Li Siguang has always disagreed with the "China is poor in oil" theory. When he once gave a report to the General Administration of Petroleum Administration, based on his own geological theory, he pointed out that there are three areas with the greatest prospects for oil exploration in China: first, the Qinghai-Kangshan, Yunnan, and Burma geosynclines; second, the Alxa-Shaanxi North Basin; third, Northeast Plain and North China Plain.

Li Siguang’s report inspired people. On the basis of a detailed analysis of the geological structural characteristics of these three oil-bearing prospect areas, he clearly proposed that the Qaidam Basin, Heihe area, Sichuan Basin, Yishaan Platform, North China Plain, Northeast Plain and other areas should be first used as the search for oil. object. In March 1956, he became director of the National Petroleum Geology Committee. Under his guidance, the national oil census began. Through censuses, oil-bearing prospect areas have been discovered in various parts of the country.

According to Li Siguang's theory, the Chinese oil army entered the Songliao Plain and began the Daqing Oil Battle. Facts have proved that Li Siguang's analysis is scientific. 1960 was the most difficult year for New China. However, in this year, a major victory was achieved in the Daqing Oilfield Battle. From the late 1950s to the 1960s, the exploration department successively discovered large oil fields such as Daqing Oilfield, Dagang Oilfield, Shengli Oilfield, and Huabei Oilfield. At a time when a large amount of energy was urgently needed for national construction, due to the hard work of the vast number of geologists, rolling oil emerged. This not only removed the label of "China is poor in oil", but also gave Li Siguang's original geomechanics theory the most powerful support. prove.

On December 20, 1964, the Third National People's Congress opened in Beijing. As a people's representative, Li Siguang attended this event. During the meeting, Chairman Mao Zedong personally received him. As soon as they met, Chairman Mao said to him kindly and humorously: "Mr. Li, you are good at Tai Chi!" Li Siguang, who was practicing Tai Chi, really thought that Mao Zedong asked him about Tai Chi, so he quickly explained Said: "I had an operation a few years ago and my health was not good. I learned Tai Chi for a while in Hangzhou, but I didn't do well." In fact, Mao Zedong's Tai Chi refers to looking for oil, which is a reference to Li Siguang's discovery of oil for China. Full recognition of the contribution made.

At the Third National People's Congress, Zhou Enlai pointed out in his government work report: "The Daqing Oilfield built in the first five-year plan was based on the petroleum geological theory originally created by our country's geological experts. Discovered through exploration." Li Siguang, who was present at the meeting, couldn't help but shed tears of excitement when he heard this.

"The two most urgent needs at present are "oil" and "uranium""

In a country where the people are the masters of the country, Li Siguang is youthful and proud, and feels that his back is stiffened. , I am confident and have a deeper understanding of the Communist Party of China. He said: "As far as a century is concerned, especially the historical experience and lessons in recent decades, only after the Communist Party appeared in China's political history did the Chinese people find the correct leadership and escape from humiliation. He lived a life of oppression and stood up in front of the whole world."

In December 1958, the party organization introduced Li Siguang to join the Communist Party of China based on his application and performance. party. Since then, Li Siguang has transformed from a national democrat to a communist fighter. At that moment, the old scientist, who had experienced two eras and a bumpy journey, was intoxicated. He felt that great happiness was embracing him. Li Siguang, who was approaching his seventies at the time, actually said that he was "like a newly born baby, a new starting point in life has just begun." He seemed to possess infinite strength and devoted himself to the upsurge of socialist construction with great energy.

When it comes to the nuclear industry of New China, many people can name a list of scientists, but if there is no Li Siguang in it, this list will at least be incomplete. Li Siguang proposed "atomic fission" as one of the natural energy sources in the early 1920s. He believed that uranium ore was a rare radioactive deposit that often occurred in areas with complex geological structures. In the 1930s, he sent students to Guangxi to investigate uranium mines, and discovered uranium phosphate, fatty lead uranium and pitchblende for the first time. This work was later interrupted due to the war and the actual utilization schedule was temporarily unavailable.

In the summer of 1953, Li Siguang went to Beidaihe for recuperation, and Zhu De, Li Fuchun and others were also there. Li Siguang has the habit of observing geology while walking. One day, while walking along Beidaihe Beach, he discovered a pile of black sand. Local fishermen told him that during the Japanese occupation, a lot of this black sand was dug up. That night, Li Siguang sent someone to Beijing with a letter to ask Qian Qianqiang to borrow instruments for testing, and immediately reported the matter to Zhu De. Zhu De proposed that the investigation of radioactive mineral resources should be started as soon as possible.

The next year, Li Siguang set up a second office in the Census Committee of the Ministry of Geology, specifically responsible for the investigation of uranium resources. This was equivalent to continuing the work he wanted to do 20 years ago but failed to start. He keenly pointed out at the 29th Academic Annual Meeting of the Geological Society: "The most urgent needs at present are the two minerals of "oil" and "uranium".

"

On January 15, 1955, Chairman Mao Zedong personally presided over an enlarged meeting of the Secretariat of the Central Committee and listened to reports from Li Siguang, Liu Jie, and Qian Sanqiang. Chairman Mao asked Li Siguang at the meeting: "Has China created Uranium ore for atomic bombs? "

Li Siguang took out the uranium ore specimen he brought with him and replied: "Yes. However, ordinary natural uranium ore has only a few thousandths of the ingredients that can be used as raw materials for atomic bombs, so a large amount of uranium ore resources and uranium enrichment plants are needed. "Li Siguang and others conducted an on-site measurement of the ore specimen in front of the central leaders. As soon as the detector approached the ore, a signal was generated.

Chairman Mao was very happy to see this and said: "Our country It is now known that there are uranium deposits, and further exploration will surely find more uranium deposits. In the past few years, there were so many other things going on that it was too late to catch up on this matter. Now is the time, time to catch. As long as we have people and resources, we can create any miracle. ”

Since then, Li Siguang has been at the core of leading China’s nuclear industry. He served as deputy director (director Chen Yun) of the State Atomic Energy Commission established in 1956, and director of the Atomic and Nuclear Science Committee of the Chinese Academy of Sciences established in 1958. He He not only directly leads the regular work of the Nuclear Science Committee, but also personally explains and deploys it to geologists from the grassroots level. Rich reserves and high-grade uranium deposits have been discovered one after another in the three east-west structural belts he proposed.

On October 16, 1964, China’s first atomic bomb was successfully exploded. It is not difficult to imagine the extent of Li Siguang’s contribution.

Li Siguang devoted himself to earthquake research in his later years.

After returning to China, he once settled in Xiangbigou near Xiangshan in the 1960s. He was invited to see a house owned by Li Jishen in Dongdan. He felt that the house was too luxurious and inconsistent with his usual life interests. , then gave up. After that, he personally selected the site, designed it, and the state built the small building in the north of Zizhuyuan. This is a two-story building with a total construction area of ​​989.1 square meters, surrounded by courtyard walls and a courtyard gate. Facing north, the building gate faces west. The courtyard has winding paths and is decorated with rockeries, fountains and fruit trees.

Li Siguang is a geologist, so when he chooses a place to live, he must pay attention to the "water and soil" and the environment. This is true for the nose ditch, and so is the choice of this place. Judging from some of the surrounding historical sites, this is a "feng shui treasure": There is a ginkgo tree in front of the door that is thousands of years old. Someone measured the trunk circumference of this tree to be 9.8 meters. The tree is about 27 meters tall and has a shade area of ​​about 400 square meters. It is said that when Li Zicheng attacked Beijing, he tied his horse to this tree. To the south of Li's house is Zizhuyuan, to the west is Wanshou Temple and to the north is Fahua Temple. There are also the tombs of several celebrities from past dynasties, such as Gan Wen, Minister of War during the Kangxi period of the Qing Dynasty, Liu Jin, the great eunuch of the Ming Dynasty, etc.

Li Siguang moved here in 1962 and lived there until his death in 1971. He lives, works, and studies here. Some small meetings hosted by him or attended by him are often held at home. He Changgong, Liu Jingfan and other heads of the Geology Department often come to the house to report on things, so the room on the right after entering the door. The larger living room actually doubles as a conference room. It is surrounded by bookcases and sofas, with a long table and several chairs in the middle. On the side near the window are many geological specimens of the Fourth Season glacial deposits. Most of them were harvested from Li Siguang's field trips.

The office next to the living room has a glass blackboard on one end of the wall. When the geological team came back from field operations, he often used this blackboard to give explanations. Or arrange, also use this blackboard to teach geomechanics to scientific and technical personnel, this is probably a habit developed over many years of teaching career.

China is an earthquake-prone country, and Li Siguang is very interested in earthquake geology and earthquake prediction. As early as 1953, when the Chinese Academy of Sciences established the Earthquake Working Committee, he served as its chairman. On March 8, 1966, an earthquake of magnitude 7 or above occurred in Xingtai, Hebei Province, which affected the hearts of the party and state leaders. A meeting was held to discuss relevant matters, and Li Siguang participated. Based on his own research results, Li Siguang put forward insightful opinions to provide reference for the Party Central Committee's decision-making.

Strongly inspired by the Prime Minister’s two inspections to Xingtai, Li Siguang also visited the Xingtai area and obtained important first-hand information. Li Siguang proposed that the main task of seismic geology work is to detect earthquakes, where the underground "enemy" lurks, and monitor its activities, so as to protect the lives and property of the people and the safety of socialist construction.

In 1968, there were widespread rumors that a severe earthquake would occur in Beijing. Late one night, Li Siguang received a notice from the State Council to hold an emergency meeting. When he arrived at the conference hall, it was already past two in the morning. Premier Zhou asked Li Siguang to sit next to him. This meeting was to study the report received by the State Council from relevant parties, saying that a magnitude 7 earthquake would occur in Beijing at 7 o'clock in the morning that day, and to request the State Council's approval to immediately notify residents to move outdoors. The matter was of great importance, so the Prime Minister invited Li Siguang here just to hear Li Siguang's opinion.

Li Siguang listened carefully to the reports from relevant parties, and called some observation stations in the Beijing area to ask if there were any abnormalities. All places responded that there were no abnormalities. At this time, Li Siguang told the Prime Minister that based on long-term observations of geostress in Xingtai and other areas, there would generally be changes in the event of a major earthquake. According to the observation results of various observation stations in Beijing, it is not necessary to issue an alarm tonight, but of course we must pay close attention.

Premier Zhou felt that Li Siguang's analysis was reasonable, so he agreed with Li Siguang's opinion and did not issue an alarm that night. Facts have proved that Li Siguang's judgment was correct, and Beijing avoided an unnecessary action.

Li Siguang’s scientific research results played an important role in the decision-making of the Party Central Committee and also attracted the attention of Chairman Mao Zedong. One day in May 1969, Li Siguang was asked to talk by Chairman Mao. 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 the books you wrote. Can you send me some books? He asked Li Siguang to help collect some domestic and foreign scientific information.

Li Siguang asked: "What scientific information do you want to see?"

Chairman Mao drew a big circle with his hand and said: "This is the information within your research scope."

p>

Li Siguang was very moved and thought this was Chairman Mao's concern for the scientific cause. Therefore, Li Siguang personally selected and compiled seven scientific materials and sent them to Chairman Mao and other leaders.

Li Siguang is the first vice president and academician of the Chinese Academy of Sciences (formerly known as a member of the academic department), chairman of the National Federation of Science and Technology, the first chairman of the China Association for Science and Technology, vice chairman of the World Association of Scientists, and the first member of the National Committee of the Chinese People's Political Consultative Conference. Second, third and fourth vice-chairmen. He is a versatile scientist. He not only writes well in prose but also in old-style poetry. Even his geology papers are also written "vividly and vividly". He also has profound musical attainments, especially the violin. In 1920, he used an 8-format 12-line music paper he carried with him in Paris to compose the violin piece "Traveling Difficulties". This was the first violin piece composed by a Chinese, with a high-pitched and strong tone in the low keynote. sound. Nearly 80 years later, at the commemorative party of Peking University’s centennial anniversary, this violin piece was played publicly for the first time. Its appearance corrects the view that Ma Sicong is the earliest violin composer in China.

Li Siguang is kind and kind to others, and does not put on airs. He treats his subordinates, staff around him, and nannies equally. Therefore, if everyone had different opinions, they were willing to raise them to him face to face without any scruples. But this doesn't mean that he lets everyone go, but he just doesn't use the training method. This also reflects the broadmindedness and self-cultivation of a great scientist.

Li Siguang still paid close attention to earthquake research in his later years. He often analyzed large amounts of observational data, and even risked a ruptured aneurysm to investigate the signs of earthquakes in the field many times. The day before his death, he sincerely said to the doctor: "As long as you give me another half year, the results of the exploration of earthquake prediction will be seen." At the last moment of his life, he left a will to his children, talking about In his last years, he often thought about issues such as earthquake prediction, geothermal utilization and marine geology. He dedicated his life's hard work to the great motherland and people!

On April 29, 1971, Li Siguang died of illness at the age of 82. Premier Zhou Enlai read Li Siguang's will with tears in his eyes at the memorial service, and everyone who listened was moved.

At the end of the memorial service, Premier Zhou instructed the staff around Li Siguang that they must sort out Li Siguang's legacy and inherit Li Siguang's scientific spirit.
