Gongsun Yan was a representative figure of the Zongheng family in the Warring States period, and he advocated the combination of unity and resistance to Qin. He served as an official in the three kingdoms of Qin, Wei, and Han throughout his life, and was highly regarded by King Huiwen of Qin during his qin state, and was appointed as Daliangzao and held the military and political power. Later, he went to Wei and Korea, why is this? What happened to him in the Qin Kingdom? Why did you always have to cooperate against Qin later?
Gongsun Yan's profession was the Zongheng family, and was the Zongheng family who had the idea of combining and conniving against Qin, and Zhang Yi was the Zongheng family who had the idea of even crossing the Qin, and the goal of the Zongheng family was to pursue his own political ideas and win political rights, which doomed the two to be violently unified, but before Zhang Yi entered Qin, Gongsun Yan was instead the top think tank of the Qin state. Gongsun Yan and Zhang Yi are also Wei people, but the Zongheng family generally has no family and country feelings, only believes in surrenderism, which country can or may show ambitions, they will go to which country, Gongsun Yan and Zhang Yi are like this. Gongsun Yan was a native of the Wei state of Yin and Jin, located in Hexi, which was a key area of contention between Qin and Wei, and in history it accidentally belonged to the State of Qin and the State of Wei by chance.
In fact, Gongsun Yan is a person who thinks for himself, only considers his own interests, he did not consider the land of our Qin state, he let the king give up attacking the land of the State of Wei at this time, at this time the State of Wei is the easiest stage to attack and the best to attack, if you give up at this time, if you want to attack the State of Wei later, it will be more difficult, and King Huiwen of Qin feels that what Zhang Yi said is very reasonable, so he listened to Zhang Yi's advice, at this time Gongsun Yan saw that he had no foothold in the State of Qin. King Huiwen of Qin had discovered that he was not wholeheartedly loyal to the State of Qin, so he secretly fled and came to the State of Wei to serve the King of Wei.
Gongsun Yan repeatedly lost many battles and once again formed a five-nation alliance to attack the state of Qin, which was Han, Zhao, Wei, Yan, and Chu. However, this alliance was not strong, and everyone did not share the same hatred and were thinking about how to preserve their strength; therefore, the menacing Five Kingdoms Alliance was actually pregnant with ghosts, vulnerable to a blow, and collapsed at Hangu Pass. The Five Kingdoms of Qin were messed up again, and the State of Wei was completely disappointed in Gongsun Yan. Gongsun Yan went to Korea to become a minister, how nai Nai Qin has become a climate, Gongsun Yan is difficult to support, his own ideas can not be responded to, and he has to taste the bitter fruit of failure again. Gongsun Yan was not born at the right time, half of his life was cut down in Qin, and he was repeatedly defeated in battles; but Gongsun Yan was unswerving and his spirit was commendable.
