After inheriting his father's position, mengchangjun recruited a wide range of door guests, and the door guests he recruited were Yulong and mixed, including guests from other vassal states and prisoners fleeing. Sima Qian went to Xuedi, the fiefdom under the jurisdiction of mengchangjun, and saw that there were many local ruffians and hooligans, which were quite different from the local customs of Zou Di and Lu Di. He asked the local old people why. They all said that when mengchangjun recruited four disciples, many evil people took the opportunity to come here.
Therefore, during the decades when mengchang Jun was in charge of Xuedi, his fiefdom was not only a place for princes and guests to yearn for, but also a place for criminals in nearby countries. When all kinds of people gathered in Xuedi in a short time, his goal was achieved - "guests are getting better and better, and fame is known to the princes!"
Knowing that King Zhao of Qin believed in the slander and wanted to kill himself, mengchang fled the state of Qin and came to the state of Zhao.
At this time, mengchangjun suddenly wanted to meet Pingyuan Jun, a famous person of Zhao state who was also famous in other countries but never met before, so he came to Pingyuan Jun's fiefdom. Knowing the news of mengchang's arrival, Zhao people, who are nearly a hundred miles away, come to the city where Pingyuan Jun is. They wait inside and outside the city gate and on both sides of the street to see the true face of Mount Lushan.
However, when mengchangjun and his party came out, strange bursts of laughter came from the crowd on both sides of the street, and some people pointed out to mengchangjun. Because they found that the famous idol was a short and thin man. Mengchang was furious. He immediately ordered his disciples to kill Zhao people who ridiculed him. In a moment, he killed hundreds of people and left without leaving a word.
After returning to China, under the pressure of public opinion, king Qi Min gave the position of prime minister to Mr. mengchang. However, king Qi Min did not trust him. In order to prevent him from seizing power, he had been secretly looking for an excuse to get rid of him.
After learning the news, Meng Changjun fled to the state of Wei overnight. Soon, the state of Yan sent troops to attack the state of Qi in order to take revenge on the enemy of destroying the state before. After hearing this news, the state of Wei immediately appointed mengchangjun as the Prime Minister of Wei, and asked him to unite with Qin and Zhao to form a multinational force with Yan to attack Qi. Instead of refusing, mengchangjun went all out. At last, the king of Qi Min died in the hands of Chu people, and the state of Qi almost died.
