Who can tell me the story of Su Qin and Zhang Yi, and what Lian Heng is like together?

Su Qin and Su Qin were famous military strategists in the Warring States Period. Military strategists flourished at the end of the Warring States Period. Competing for the championship requires not only the use of force, but also a diplomatic and political offensive. Strategists came into being. They don't advocate a particular idea or viewpoint, but decide their choices according to actual needs. So they use Confucianism and Taoism alternately, which constitutes the so-called "one vertical and one horizontal". The Western Han Dynasty called it "the theory of vertical and horizontal". The long theory, the short theory and the vertical and horizontal theory all have the same meaning, and they are all a way to persuade each other from different angles. By the end of the Warring States Period, it was a foregone conclusion that Qin Guoqiang was weak in six countries. Therefore, it was Hezong who United the Kanto countries to resist Qin, and Lian Heng was what Qin tried to destroy. For example, the Warring States policy set Qin and the six countries against each other, and Su Qin and Zhang Yi were always regarded as the representatives of the United strategy, and the two sides defended the interests of the six countries or Qin respectively. Han Shuzhi affirmed the advantage of "the right thing is appropriate" for strategists. However, excessive flexibility can easily lead to fraud. History books say that the six countries are "trying their best to make peace and balance the length", and Hanshu also calls it "cheating and breaking faith". Nevertheless, strategists were still valued by monarchs in the late Warring States period, so Han Fei said, "Shandong talks freely for a day." Su Qin's deeds can be found in The Warring States Policy and Historical Records. According to historical records, he was from Luoyang in the Eastern Zhou Dynasty. He went to the state of Qi to work for Mr. Guigu, and then traveled for several years without finding anything. I was laughed at by my family. So he worked hard, got the weekly book Yin Fu and read it again, and understood the mystery of how to vote for the goodness of the Lord. He first went to lobby, Qin, and others, but all failed. Then he went to Yan State to meet Yan Houwen. He accepted his alliance idea and gave him money and money to lobby in Zhao, Han, Wei, Qi and Chu. After his persuasion, the six countries joined forces and Su Qin became a "six countries". When he arrived, he died because he offended the king of Iraq. When he arrived at the king, the doctor of Qi was jealous of Su Qin and stabbed him. Before he died, he told Wang Min that after I died, I could be punished for treason, so as to find out my murderer. After Su Qin's death, his brothers, Su Dai and Su Li, also lobbied everywhere for "courting princes". When Sima Qian was writing Biography of Su Qin, he found that many records about Su Qin were not credible and wrong. However, there are still many mistakes in his handling of Su Qin's deeds, especially in the age. For example, when Su Qin first lobbied Zhao, Yan and other countries with Yan, he set his own death year before Yi Cheung. After many scholars' textual research, it is clear that Su Qin should be among the six countries active in the era of Yan Zhaowang and Qi Min, and the famous figures in the same period include Meng Changjun, Li Dui and Zhou Zui. Su Qin served as an official in Yan, and his main activity was to alienate the relationship between Qi and Zhao, so as to reduce the pressure of Qi on Yan. With Nye against * * *, joint five countries against the state of Qin. Later, he left the State of Yan and went to the State of Qi, where he was highly valued, but Su Qin remained loyal to the State of Yan and secretly helped it. The strategy he adopted was to persuade Qi to attack the Song Dynasty, so as to divert Qi's attention from Yan. So the faction suddenly attacked Qi, and Qi was caught off guard by Yan. At this point, the activities of Su Qinyin and Yan Moqi were exposed, and Qi was sentenced to a car crack, which was a sensational event at the end of the Warring States Period and was reflected in many writings at that time. For example, in Sun Tzu's The Art of War, a bamboo book unearthed in Yinhuan Mountain, Shandong Province, there are words like "Yan is also prosperous, and Su Qin is in Qi". For example, Lu Chunqiu said that "Qi used Su Qin, and the world knows its death". These records show that during the Warring States Period, everyone knew that Su Qin was an official for Yan, which eventually led to the demise of Qi and the prosperity of Yan, but he also made sacrifices for Yan. Su Qin was a famous soldier at the end of the Warring States Period. Xunzi and Chen Dao compared Su Qin of Qi with Zhou Hou of Chu and Zhang Yi of Qin. In the Western Han Dynasty, Su Qin was still praised by people. For example, Biography of Historical Records and Zou Yang praised him as a loyal minister of the State of Yan. Huai Nan Zi also mentions him in many places, affirming that he has the advantage of knowing tactics. Sima Qian thinks that Su Qin has shown his extraordinary intelligence in the process of "connecting six countries with relatives". There are thirty-one pieces of perilla in Hanshu Yiwenzhi, which is a collection of Su Qin's works or deeds recorded by later generations, including some lobbying words of Su Dai and Su Li. Perilla is the longest among military strategists. It can be seen that from the Warring States to the Western Han Dynasty, the works or related materials belonging to the Su brothers among military strategists are very weighty and the most widely circulated. After the Han Dynasty, the book died. Among the silk manuscripts unearthed from Mawangdui Han Tomb in Changsha, there are eleven letters from Su Qin to the prince of Yan or the prince of Zhao, which are not found in the ancient books handed down from ancient times such as Warring States Policy and Historical Records, and two others are partially found in Warring States Policy, which are important new materials for understanding Su Qin's deeds now. Zhang yi. The descendants of Wei nobles who studied vertical and horizontal techniques lived mainly before Su Qin, and were famous politicians, diplomats and military strategists in the Warring States period. During the Warring States period, there were many countries, and vassals fought for hegemony and separatist wars frequently. The vassal States adopted the strategy of "uniting the horizontal" in diplomacy and military affairs. Or "vertical integration" and "uniting the weak to attack the strong" to prevent the merger of powerful countries, or "Lian Heng" and "attacking the weak with the strong" to achieve the purpose of annexing land. As an outstanding strategist, Zhang Yi appeared on the political stage of the Warring States Period, which had a great influence on the situation changes in the merger wars of various countries. In the ninth year of Qin Huiwen (the first 329 years), Zhang Yi entered the State of Qin from Zhao Guoxi. With her outstanding talent, she was appointed as the guest minister of Qin to plan a strategic attack. The following year, following the example of Shanxi bureaucrats, Qin began to set up a phase, which was called a phase list or, and Zhang Yi held this position. He was the first prime minister after the Qin Dynasty, the first of 100 officials, and participated in military, political and diplomatic activities. From then on, he began his political, diplomatic and military career. After paying homage to the Prime Minister, Zhang Yi actively planned for the State of Qin. He used Lian Heng's technique to force Han and Wei governors to worship Qin, and together with Gongzi Hua (Sang), he captured Puyang (now Xixian County, Shanxi Province). He also lobbied Wei to take 15 county without a single soldier, and Shaoliang (now Hancheng, Shaanxi Province) was dedicated to Qin. In the 13th year of Qin Huiwen (the first 325 years), Zhang Yi led an army to capture Shaanxi County of Wei (now Shaanxi County of Henan Province). In this way, the Yellow River natural barrier was occupied by the State of Qin. With the continuous growth of Qin's power, Zhang Yi assisted Qin Huiwen as the king, and the power of Qin became stronger and stronger. In the second year of Qin Huiwen's reign (323 BC), in order to resist the policy of uniting with the Communist Party and achieve the goal of annexing Wei's territory, Zhang Yi used Lian Heng's strategy to meet with Minister Qi and Chu in Sangzi (now southwest of Pei County, Jiangsu Province) to eliminate the anxiety of Qin's eastward advancement. Zhang Yi returned to the State of Qin from Sang Mu and was relieved of his post. During these three years, due to the alliance of Hui Shi and the failure of Chu, Wei had to take Zhang Yi as a phase in an attempt to attack Chu in conjunction with Qin and Han Dynasties. In fact, Zhang Yi's ultimate goal is to make Wei a leader attached to Qin. Due to Lian Heng's threat to other countries, Qin Huiwen was king of Yuan Geng for six years (the first 3 19), and Gongsun Yan, the state of Wei, became king with the support of Qi, Chu, Korea, Zhao and Yan. Zhang Yi was deported to the State of Qin. In the eighth year of Qin Huiwen and Wang Ba-nian (the first 3 17), Zhang Yi was appointed as Qin Taishou again. In nine years, King Hui of Qin accepted Sima Cuo's suggestion and sent Zhang Yi, Sima Cuo and others to attack Shu, winning, and then destroyed Pakistan and Canada. In this way, Qin occupied a rich land of abundance and had a consolidated rear area, which provided favorable conditions for Qin's economic development and military war. In the 12th year of Yuan Geng (3 13 BC), the king of Qin wanted to attack Qi, but worried about the alliance between Qi and Chu, so he sent Zhang Yi into Chu to lobby Chu Huaiwang. Zhang Yili lured him, saying, "Chu is absolutely Qi, and Qin is willing to spend 600 Li on commercial land." Chu Huaiwang listened to his words, broke off relations with Qi, and sent people to Qin to receive land. Zhang Yi said to the envoy of Chu, "I have been with the king for six miles, but I have never heard of it for six hundred miles." The emissary of Chu returned to Chu and told Chu Huaiwang what Zhang Yi said. In a rage, Chu Huaiwang rose up and attacked Qin. In the 13th year of Yuan Geng, King of Qin Huiwen (the first 3 1Z), Qin Jun defeated the Chu army in Danyang (now north of Danshui in western Henan), and more than 70 people, including Qu Gai, captured Chu Hanzhong, took a land of 600 Li and set it as Hanzhong County (now Han Middle East in Shaanxi). In this way, Bashu and Hanzhong of Qin State are connected together, which not only eliminates the threat of Chu State to Qin State, but also expands the territory of Qin State and strengthens its national strength. "Biography of Zhang Yi in Historical Records" said: "People in Sanjin often have accidental events, and those who talk about Qiang Qin are generally people in Sanjin." There is no doubt that Zhang Yi is one of the most outstanding. In the 14th year of King Huiwen of Qin Dynasty (3 1 1 years ago), Zhang Yi lobbied in Chu, Han, Qi, Zhao and Yan, and made the five countries Lian Heng pay attention to Qin. In the same year, Zhang Yi was awarded the title of Wuyi in Wu Xinjun. On the basis of Shang Yang's political reform, Zhang Yi "resisted the vassals abroad", cooperated with Qin's agricultural policy, lobbied the vassals with eloquent eloquence and simple strategy, and made many achievements, becoming a decisive figure in Qin's politics, diplomacy and military affairs. In the ever-changing and treacherous environment, he mainly relied on diplomatic means and adopted Lian Heng's strategy to "disperse the followers of the six countries and make them take care of Qin in the west", which greatly expanded the national prestige of Qin and had a great deterrent effect in the vassal States. Jing Chun, a disciple of Mencius, praised him and said, "Gongsun Yan and Zhang Yi are real men! Anger is the fear of the princes, and peace is the destruction of the world. " Zhang Yi used military and diplomatic means to make Qin "take the land of Sanchuan, combine Bashu in the west, take the county in the north and Hanzhong in the south", which played a positive role in Qin's hegemony and future reunification. In the 14th year of Qin Yuan Geng (the first 3 1 1 year), Qin died of illness and his son acceded to the throne. Zhang Yisu was dissatisfied, abandoned Qin for Wei and died in Wei.
