He is one of the pioneers of geology in China, founded geomechanics, and made important contributions to the development of petroleum industry in China. In his early years, he had a superb study on Odonata fossils and their stratigraphic stratification significance. It is suggested that there are Quaternary glaciers in eastern China. This paper studies the crustal movement and its relationship with mineral distribution from the mechanical point of view, and establishes new concepts of geomechanics and tectonic system. Throughout his life, he advocated studying the occurrence, development and combination of geological structures from the perspective of mechanics, and believed that various structural characteristics were the result of in-situ stress activities, and established the concept of "structural system" and geomechanics school. The discovery of Daqing and Shengli oil fields confirmed that the tertiary subsidence of Neocathaysia has broad oil and gas exploration prospects. It creates a method of earthquake prediction by combining active structure research with in-situ stress observation. Astronomy, Geology and Paleontology published in his later years had a far-reaching impact on the interdisciplinary advocacy in China. It has made great contributions to the development of geological education, geological science and geological undertakings in China. 1955 was elected as a member of China Academy of Sciences. He is the author of The Main Causes of Image Changes on the Earth's Surface, China North Training Project, China Geology, Lushan Mountain in the Ice Age, Introduction to Geomechanics and Anthology of Astronomy, Geology and Paleontology. 1971On April 29th, Li Siguang died of illness at the age of 82.

Since the history books of all countries were burned by Qin Shihuang, the following is the only historical data about Lian Po.
Summary:
Lian Po was an outstanding military general of Zhao in the Warring States Period. The main activities were in Huiwen, Zhao Haoqi (298-266 BC), Cheng Xiao, Zhao Haoqi (266-245 BC) and Daoxiang, Zhao Haoqi (245-236 BC). It is one of the four famous soldiers in the Warring States Period!
At the beginning of Zhao Huiwen, Qi was the most powerful of the six eastern countries, and Qi and Qin were both powerful countries in the East and the West. When he wanted to expand his power in the East, Zhao was the first person to do so. In order to remove obstacles, the king of Qin sent troops to attack Zhao many times. Lian Po led the army of Zhao to defeat many times, forcing Qin to change its strategy and implement the alliance. In the fifty-fourth year (the first 285 years), King Huiwen made peace with Zhao in Zhongyang (now the west of Zhongyang County, Shanxi Province). In order to unite Korea, Yan, Wei and Zhao to crusade against Qi, the Qi army was defeated. Among them, in the 16th year of King Huiwen (the first 283 years), Lian Po led the Zhao army to cut Qi, marched straight into Qi, captured (now Dancheng West, Shandong Province, was originally a patriotic territory, and later belonged to Qi) and became a vassal, and Ye Zhao became the first of the six countries. Lian Po moved troops back to Korea and worshipped Shang Qing (Shang Qing was the highest-ranking civil servant at that time, equivalent to the later prime minister). The State of Qin did not want to rashly attack Zhao, only because of Lian Po's power. Since then, Lian Po led the army to fight, held his ground and captured it, and almost won every battle, which had a great influence on other countries.
In the thirty-second year of Zhou Nanwang (Zhao Huiwen's sixteenth year, the first 283 years), Qiang Qin was willing to exchange fifteen cities. Zhao sent Lin Xiangru to the State of Qin, and Lin Xiangru was just a "Scheeren" under the eunuch Miao Xianmen. After Miao Xian recommended to King Huiwen, he took the "Choi of Harmony" and became the envoy of Zhao to the State of Qin. With great wisdom and courage, Lin Xiangru returned to Zhao intact and won the diplomatic victory over Qin.
Later, Qin conquered Zhao and occupied Shicheng. In nineteen years, King Huiwen attacked Zhao again, killing twenty thousand troops of Zhao. At this time, the king of Qin wanted to make peace with the prince of Zhao in Mianchi (now Mianchi County, Henan Province). The prince of Zhao was afraid and didn't want to go. Lian Po and Lin Xiangru negotiated to show Zhao's strength and courage. Zhao Wang walked with Lin Xiangru, and Lian Po saw him off. He said to the prince of Zhao, "Your Majesty's visit is only thirty days. If you don't pay it back in 30 days, please ask the prince to blackmail Zhao Zhiwang by breaking Qin. " Lian Po's general demeanor and careful arrangement strengthened the image of the prince of Zhao. At the same time, because he was as humble as Mianchi when dealing with the king of Qin at the meeting, he responded to the various means used by the king of Qin without weakness, which not only saved the reputation of the king of Zhao, but also shocked the king of Qin and his ministers. Finally, Zhao Wang returned safely.
After the meeting, the prince of Zhao "made great contributions to each other and worshipped him as Shangguan", ranking above Lian Po. Lian Po was dissatisfied with Lin Xiangru's title of Shangqing, thinking that he, as a general of Zhao, had made great contributions by attacking wild cities and expanding territory, while Lin Xiangru, who was in a low position, was above me just by talking, which was intolerable. He publicly threatened to humiliate Lin Xiangru in public. After Lin Xiangru knew it, he didn't want to compete with Lian Po, but adopted a forbearing attitude. In order not to make Lian Po rank lower than himself in the imperial court, he always admitted that he was ill every time he was in the imperial court. Sometimes when Lin Xiangru goes out by car and sees Lian Po coming from a distance, he simply leads the car to avoid it. This aroused the dissatisfaction of Lin Xiangru Scheeren, and Lin Xiangru explained: "Compared with Lian Po, Lin Xiangru Qiang Qin, the covetous king of Qin, dared to scold him in court and humiliate his ministers. Will I still be afraid of Lian Po? The reason why we dare not send troops to Zhao is because Lian Po and I are both DPRK officials. If we fight with each other, it's like killing two birds with one stone. The reason why I avoided him was nothing more than putting the national crisis above personal grievances. " Upon hearing this, Lian Po was deeply moved. He chose the day when Lin Xiangru had the most guests. With thorns on his back, he came to Lin Xiangru's house with bare arms and demanded that Lin Xiangru be punished. From then on, the two became friends, living and dying together.
The story of "harmony but difference" was expressed by later generations in various literary forms, and its strong patriotic feelings made people cry and moved people to work hard. And Lian Po has the courage to change, sincere and frank personality, which makes people feel more amiable and lovely.
In the twentieth year of Zhao Huiwen (278 BC), Lian Po conquered an army of Qi. In the second year of Zhao Huiwen's twentieth year (276 BC), he cut Qi again and captured Jiucheng. The following year, Lian Po attacked Wei and captured Fangling (now twenty miles south of Anyang, Henan Province) and Anyang City (now forty-three miles southwest of Anyang County, Henan Province). It is precisely because of Lian's friendship with Lin that Zhao was United and devoted to serving the country that Zhao was once powerful and became a barrier for eastern governors to stop Qin from advancing eastward. /kloc-Qin did not dare to attack Zhao in 0/0.
In 266 BC, Zhao Huiwen died and became king. At this time, at the request of Fan Ju, the State of Qin adopted the strategy of "making friends with Qi and Chu", and at the same time attacked small neighboring countries. In the fifty-fifth year of Zhou Nanwang (260 BC), the State of Qin attacked Shangdang in North Korea. The south Korean defenders attending the banquet were helpless, so the satrap dedicated the banquet to Zhao. As a result, there was a war between Qin and Zhao in Shangdang area. At this time, Zhao She was dead, Lin Xiangru was seriously ill, and only Lian Po was in charge of military affairs. So, Lian Po was ordered to command two hundred thousand Zhao soldiers and keep them out of Changping (now northwest of Gaoping County, Shaanxi Province) (see the battle of Changping). At that time, Qin Jun had taken the wild king from the south (now Qinyang, Henan) and slightly joined the Party from the north (now central Shanxi), cutting off the connection between Changping and the south, and his morale was high. The Zhao army came from afar, not only at a disadvantage, but also at a passive disadvantage. Faced with this situation, Lian Po correctly adopted the operational policy of establishing base areas to hold on, consuming the enemy and attacking the enemy with cameras. He ordered Zhao to build a tight barrier by virtue of mountain hazards. Despite Qin Jun's several challenges, Lian Po always shuts the crowd out. At the same time, the people in Shangdang area were concentrated, engaged in battlefield transportation, and committed to building fortifications against Qin. Zhao heavily guarded, unable to meet the challenge, and his spirit gradually lost. In order to defeat Qin Jun's plan of a quick victory, Lian Po fought hard and persisted for three years. Seeing that it was impossible to make a quick decision, Qin persuaded the prince of Zhao with trickery. What Qin was most worried about and afraid of was to replace Lian Po with Zhao Kuo. Zhao Wang was eager to win, and finally fell into a trap. He thinks that Lian Po is afraid of war, forcing him to resign from Lian Po and use Zhao Kuo as his general. Although Lin Xiangru protested that Zhao Kuo, an armchair strategist, was not suitable for this post, the prince of Zhao did not listen and appointed Zhao Kuo as general. After Zhao Kuo replaced Lian Po, Lian Po's strategic plan was completely changed and many officers were replaced. Seeing that Zhao Kuo became a general, Qin secretly asked Wu's troops to attack Zhao. In Changping, he defeated the Zhao Kuo army, shot and killed Zhao Kuo, and trapped more than 400,000 Zhao soldiers. In the battle of Zhao Changping, Zhao lost nearly 500 thousand elite troops.
After winning the battle, Qin Changping accepted Zhao's request for peace. Reason: Although Qin won the battle of Changping, nearly half of the people were killed and injured, and the domestic food consumption was almost the same. Qin was unable to further occupy Handan and destroy Zhao. Two foot soldiers have been fighting outside for a long time and their morale is low. The front line is too long and it is difficult to supply. In addition, the newly occupied land is prone to chaos and rebellion may occur at any time (the consequences will be chaotic). All three Wei Chu were ready to move, and their flanks were quite unsafe (which was also the reason for the later Qin Dynasty). Therefore, Qin accepted the request.
Zhao later had differences on land division, so I won't say the details. In the end, Wang Zhao decided not to fulfill the peace treaty and actively prepared for war. All this eventually led to the outbreak of the Qin-Zhao-Handan War. Zhao Haoqi, the king of Qin, was furious and led his troops to attack Zhao. Among them, I think there are three reasons why Leitian didn't go to war: First, Qin won the battle of Changping, and I appreciate the tenacious fighting will of the people of Zhao. This is different from the tenacity of the pool. Qin Bing's tenacity is that he can win titles and land by inducements, while Zhao Bing's tenacity stems from his innate national temperament and martial tradition. Second, the soldiers of Qin suffered heavy casualties, especially the elite troops (light soldiers, cavalry, chariots and crossbowmen) who mastered the skilled combat technology. At this time, most of the main forces of Qin were just the lower classes with limited fighting capacity. It is even more dangerous for the safety of the flank. If Qin attacks Zhao, it may be surrounded by Wei-Chu allied forces at any time. Third, I am quite dissatisfied with the obedience of the king of Qin to Fan Xiang. However, the confident King of Qin believed that Qin Jun was invincible, even though he sent 650,000 troops to attack Zhaohandan.
Zhao's preparation for Qin Jun's attack can be said to be the acme. Because of the loss of Zhao's elite troops, Zhao was unable to carry out field operations and turned to guarding the city, and hoarded a lot of food and equipment for this purpose. At the same time, diplomacy is also actively carried out. Out of guilt for Changping's defeat, Zhao Zhi and Ping Yuanjun also actively lobbied Wei Chu to organize the defense of Handan.
The war has begun. ....
In January of the forty-eighth year of the Qin Dynasty, Qin Ju had about 500,000 soldiers, who were divided into three ways. Sima Geng led an army to attack Korea and Taiyuan on the left, taking the place of the party, so that the main force of North Zhao could not go south; On the right, about 100,000 troops were sent to Nanyang to reject the Wei-Chu Coalition; The middle route army, about 300 thousand people, went straight to Handan and Zhao. In July and August, the only strategic barrier that Zhao An and Pillau could rely on was breached by Qin. In October, soldiers surrounded Handan, which was the seventh year of Zhao's reign.
Regarding the attack on Zhao from January to August in 1948, Zhao adopted the following strategies: building a wall to clear the field, abandoning fields and satellite cities, concentrating garrison troops and grain all over the country, and defending the capital Handan with all his strength. At this time, Zhao's elite soldiers had been killed in the battle of Changping, and there were about 300 thousand to 400 thousand foot soldiers in Handan. Among them, most of the soldiers are old people around 40 years old (40 years old in ancient times) or weak children between 13 and 18 years old. The young and strong foot soldiers do not exceed 1 00000, including Wang Zhao's guard infantry and a small number of cavalry, about10000 to 20000. These constitute the main force of Zhao's surprise attack on Qin Jun day and night. Garrison commanders Lian Po, Gong Wei and Ping Yuanjun Zhao Sheng were the actual supreme commanders of the Battle of Handan. At the same time, due to the battle of Changping, the people of Handan, Zhao, lost their children, husbands and fathers, so they United as enemies and swore to defend Zhao.
Qin Jun takes the tomb of five generals as the general, with an army of about 300,000. Based in Wu 'an, it surrounds Handan and Qin Jun and has a large number of siege equipment. At the gate of Handan, the fertile land in the area around the tomb of the Fifth Doctor of Qin Dynasty was completely destroyed by the Zhao people. The tomb owner thinks that he captured Chu Duying in 29 years, captured the girder in 32 years, and Zhao Zhuli was killed last year. At this time, Zhao Handan's defenders were just old, weak and sick, and they could capture them in just a few months. But when he saw the magnificent and generous wall of Handan and the soldiers of Zhao standing on the wall, he found that Zhao's face clearly showed an expression of never giving in and never taking revenge. I feel uneasy in my heart This year is forty-nine years for King Qin Zhao and seven years for Zhao Haoqi Cheng Xiao.
In autumn and October of forty-nine years in Qin Zhao, the tomb of five generals led an army to attack Handan City. Qin crossbowmen shot hundreds of thousands of arrows in Handan city to cover the siege of infantry. The infantry was divided into two teams, one with a ladder on its shoulder, and the other with a cart heading straight for the gate of the capital city of Zhao. The three armies attacked the capital city of Zhao day and night. But a month later, Qin Jun killed five field officers alone, with nearly 20,000 casualties. Instead of stopping to rest, he turned to launch a small-scale attack to capture Zhao Zhi. On the contrary, Zhao repeatedly attacked elite infantry and even a small number of cavalry constantly raided Qin's barracks around Handan, causing heavy casualties to Qin. On the contrary, Qin Jun is on guard day and night, and many soldiers are slack.
The situation on the front line in Handan soon reached King Zhao of Qin, and King Qin Zhao was very angry. This Wu Anjun was too ill to go. On the one hand, he ordered the tomb to gather troops to capture Handan as soon as possible, and on the other hand, he organized reinforcements.
In the forty-eight years of Qin Dynasty, in the cold wind of December, the letter was received, and the second large-scale siege war was launched against Handan, the capital of Zhao State. However, under the bow and crossbow of Zhao State, the soldiers suffered heavy casualties and the situation was unfavorable. Zhao sent troops to attack it, and Qin was dozens of miles away. There are about 5000 casualties in this battle.
In Handan, Zhao Zhi, the wounded are all over the city, but the morale of the soldiers is still high. In the cold winter, Zhao Sheng, a plain army, accumulated food and clothes in the house and scattered Zhao Min, saving his family. General Lian Po and Jia Shangcheng personally directed the bidding, and Ping Yuanjun Zhao Sheng also went. Zhao Wei, Lian Po ordered the weak to build the city, while the strong took turns to stop the city every battle, and ordered the good shooters to gather and shoot Qin. During this period, some elites often went out of the city, and many of them didn't come back (died in battle), but Qin also suffered heavy casualties.
In the first month of the forty-ninth year of Qin Zhao, 100,000 Qin reinforcements arrived in Handan with a large number of soldiers, hay and the last order of the king of Qin. The five doctors' tombs adjusted their forces to launch the third attack on Handan, which was also the largest since the attack on Zhao.
In the first month of the forty-ninth year of Qin Zhao, General Wang Bi led hundreds of soldiers and took a large number of soldiers to Handan to prepare food and grass. Wudu Fuling adjusted its forces and prepared to attack Handan for the third time, which was also the largest attack since the attack on Zhao. It is believed that the tomb has already known the discontent of the king of Qin and the omen of replacing it with Wang Bi, so it is certain that Wang Lingjun's third attack is quite fierce.
The war broke out in the first month, which was still the winter in the north. At this time, Handan has been besieged for nearly four months, and the loss of troops and food supply in the city has become a crisis, and people's hearts are more fragile in winter. But under the guidance of Lian Po and Yue Cheng, Zhao's morale is still high. At the same time, Qin Jun's morale began to rise after being reinforced. After more than a month of fighting, Zhao resisted the attack to the death and won. Qin Jun suffered heavy casualties, and his foot soldiers complained bitterly. The king of Qin was not good at bullying, so he was spared, and Wang Bi took the place of general. Later, Wang Bi led the army to attack Handan for nearly five months, but it was still not captured. In October, after the king of Qin killed Bai Qi, he ordered Zheng Anping to lead 50,000 troops to support Wang Bi. At this time, when the situation in Handan was the most critical, the supply of food and grass had already been cut off. Everyone was "cooking with bones" and "cutting children to eat", and Zhao Jun was still indomitable. At the same time, Ping Yuanjun's diplomatic war began to play a role. By the beginning of December, 100,000 troops of the Eighth Wan Chu Army in Wei Jun had reached the periphery of Handan, and the State of Qin was constantly sending more troops to Fencheng (the land of Hedong) to show unity, and the war between the two sides was imminent. In December of the same year, Xin commanded the Wei-Chu allied forces and launched a powerful offensive against Qin Jun. Wei Jun attacked the west, Chu Jun attacked the east, and Zhao Jun was attacked on three sides, and the whole line collapsed. Wang Bi led Qin Jun's main force to retreat to the west for hundreds of miles, only taking a short break when entering Fencheng. About 20 thousand people in Zheng Anping's department in the south of Handan were besieged by Zhao. Zheng Anping's department was far away from the main force, and there was no hope of breaking through, so he had to surrender to Zhao. When the allied forces of the Three Kingdoms attacked Fencheng, Qin Jun was defeated and forced to retreat to Hexi for confrontation. The allied forces seized the opportunity to recover the land 600 miles east of the river, which was very shocking.
After losing the battle of Changping, Zhao lost nearly 500 thousand troops. Since then, the combat troops can be divided into these parts: the county garrison is the representative to defend against Xiongnu and Yan, the standing army of about 50,000 people in wartime can be expanded to100,000 people, and Jinyang garrison (the old capital of Zhao) is the right wing of Zhao, the springboard to attack Qin flank and the gateway to North Zhao, and the standing army of about 70,000 people. Zhongmou (including Tunliu) garrison left-wing resistance outpost and Wei fortress, standing army of 30 thousand people. Zhao's defense center in Handan was divided into Wu 'an garrison and Wucheng garrison because of repeated wars in Handan. Generally speaking, the standing army in Handan is about100000. Because of its strategic position, Handan has become one of the cities with the most frequent wars and the most complete military defense. The battle of Handan, Zhao was in danger, but under the command of excellent generals of Zhao, with the tenacious resistance of Zhao soldiers and the support of Zhao people, it was all resolved one by one. It can be seen that Zhao's unique temperament, different from the six countries, is more solemn and stirring, strong and unyielding, and United.
As for the battle of Handan, I think it is as tragic as the battle of Stalingrad and the battle of Berlin. Qin directly and indirectly used about 650,000 troops against Zhao, including 450,000 troops against Handan. More is the strength comparison between the two sides. As mentioned earlier, after the battle of Changping, Zhao's strength and national strength were greatly reduced, and there were only 100,000 combat troops in Handan. Surprisingly, Qin Jun can keep its capital intact under constant siege and attacks. The battle of Handan was not so much a victory for Zhao as a victory for Zhao Min. Under Zhao's democratic rule, the people of Handan paid a heavy price for defending Handan. "Hundreds of thousands of Zhao died, but Handan was only spared by the city" is so tragic. Imagine that before the war, troops and grain from all over Zhao gathered in Handan, and the people of Zhao joined forces to build the city day and night and sharpen their knives. What a spectacular sight. This shows how important it is for a country, a nation and an army to have a generous and sad temperament, a martial tradition and an atmosphere of unity and forge ahead.
