Because of his profound knowledge, his position was once very noble, and he offered three cups of official wine.

Later, due to slander, Gou Zi left the State of Qi and went to the State of Chu, and was appointed as the Lanling Order by Chun Shen Jun. Before long, some people thought that Gou Zi would bring danger to the State of Chu. Gouzi had to leave again to find Zhao. In the state of Zhao, the dog is regarded as an official. Later, Chun Shen Jun sent someone to take the dog back to Chu. After Xunzi returned to Chu, he was appointed as Lanling Order.

In 238 BC, Chun Shen Jun was killed and Gou Zi was dismissed from office. During his stay in Lanling, he went to Qin and Zhao, and finally died in Chu. Gou Zi was learned all his life and spread his thoughts through writing books, preaching and teaching. His theory is based on Confucianism and combines the strengths of Taoism, law, fame and ink.

Gou Zi has many students, among whom Han Fei and Li Si are famous. Both of them later became representatives of Legalists. Because of the disciple school, Xunzi has been controversial in history, and some scholars do not agree that Gou Zi is a Confucian scholar. Some scholars also criticized it. There are more than 300 works left by Gou Zi in the Han Dynasty, and Liu Xiang's editor has designated them as 32, of which the following six are considered to be entrusted by future generations.
