After Gongsun Yan was ostracized by Zhang Yi and left the Qin state, he led the Five Kingdoms to cut down qi, which greatly contained the eastward expansion of the Qin state

Gongsun Yan was originally a Native of the State of Wei and the Jin Dynasty, who had served as an official in the State of Wei in his early years, but he was not well mixed, so he left the State of Wei and went to the State of Qin. At this time, the State of Qin recruited talents, and Gongsun Yan was like a fish in the water, and soon became famous. In the thirty-sixth year of King Xian of Zhou (333 BC), Gongsun Yan led the Qin army to attack the Wei military stronghold of The State of Hexi, Diaoyin City, and defeated the Wei army. Because of his outstanding performance in this battle, King Hui of Qin was promoted to Daliangzao, which was the highest official rank in the Qin state, equivalent to the prime minister. In the face of the attack of the Qin state, King Hui of Wei cut off the land and sought peace, ceding Gongsun Yan's hometown of Yin and Jin to the Qin state. At this time, Gongsun Yan was under one person in the Qin Kingdom, above ten thousand people, and the spring breeze was triumphant. However, the arrival of a man changed his status.

The person who came was none other than Zhang Yi, the most famous cross-sectional artist. He Shengyu, He Shengliang! Both Gongsun Yan and Zhang Yi were from the State of Wei, both were masters of vertical and horizontal, both were full of desire for power, and open strife and secret struggle were inevitable. A mountain does not tolerate two tigers, the two fought for several years, and finally Zhang Yi was superior in skill and squeezed out Gongsun Yan. Gongsun Yan was furious and left the state of Qin in a fit of rage, returning to the state of Wei, where he was appointed as a general by King Hui of Wei.

After Gongsun Yan was squeezed out of the Qin state by Zhang Yi, he returned to the Wei state, and this Zongheng master was really skilled, and soon gained the trust of King Hui of Wei. At that time, Zhang Yi advocated the "continuous horizontal strategy" in the Qin state, that is, Qin allied with Qi and Chu to deal with the Three Jins. In response to Zhang Yi's attempt to "form an alliance of the three kingdoms", Gongsun Yan launched a "joint strategy" to counteract it. He meticulously planned the "Five Kingdoms And Vertical", which is the five countries of Wei, Han, Zhao, Yan, and Zhongshan, and used the joint vertical strategy to counter Zhang Yi's continuous and horizontal strategy.

Gongsun Yan

Under the auspices of Gongsun Yan, the Eastern Campaign against the Qin State was in full swing. In the second year of King Shenliang of Zhou (319 BC), under the efforts of Gongsun Yan, the Hezhong Movement made substantial progress. The following year, the five kingdoms of Wei, Zhao, Han, Yan, and Chu reached an agreement to jointly send troops and form a multinational force to attack the Qin state. The Five-Nation Alliance arrived at Hangu Pass (LingbaoBei, Henan), and the Qin army sent troops to meet the battle. The Qin army was hostile to the enemy, the momentum was compelling, the coalition army only knew how to talk about it, and when it came to the battlefield, no one would work hard. The outcome of the war was not unexpected, and the multinational coalition was easily defeated. Although the Five Kingdoms attacked Qin this time, the Eastern United Vertical Movement proposed by Gongsun Yan was still the only magic weapon for the Eastern states to deal with the Qin State.

Despite the defeat of the Combined Rebellion against Qin, Gongsun Yan was not without success. Under the rebellion of Gongsun Yan, Yiqu, who had always been subordinate to the Qin state, suddenly rebelled, leaving King Hui of Qin in a hurry. Yiqu was the state of Gu Rong, and in the thirty-eighth year of King Xian of Zhou (331 BC), unrest broke out in Yiqu, the Qin state invaded on a large scale, and the king of Yiqu was forced to submit.

After the rise of the Eastern Fusion Movement, King Yiqu sneaked to the State of Wei to meet the King of Wei. Gongsun Yan said to king Yiqu: "If China has nothing to do with Qin, then Qin will burn and win the kingdom of the king; if China has something to do with Qin, then Qin will make heavy money, and the country of the king will also be." ”

King Huiwen of Qin

The King of Yiqu immediately said that he would definitely stand on the same front as the princes of the Central Plains. As long as there is action in the East, he will launch an uprising in the West and break away from the rule of the Qin State.

When Gongsun Yan led the Five Kingdoms Alliance to cut down Qin, "Chen Zhen said to the King of Qin: 'The king of righteousness, the sage of barbarians, the king is better to bribe him to soothe his heart.'" The King of Qin said, "Goodness." "King Hui of Qin did indeed send a thousand splendid horses and a hundred beautiful women to bribe the King of Yiqu." Embroidered with a thousand horses, a hundred good women left behind a canal jun". However, king Yiqu was not moved, he remembered Gongsun Yan's warning, did not accept Bribes from Qin, and resolutely rebelled against Qin. At this time, the elite generals of the Qin state were all transferred to the eastern front, and the western front was insufficient, so they had to temporarily put together a miscellaneous army to meet the Yiqu, and they were defeated and returned. For a long time after that, Yiqu had always been a problem for Qin's confidants, and Gongsun Yan's rebellion against Yiqu greatly restrained Qin's expansion in the east.
