"Human nature is evil, and good people are false" is the central idea of inherent vice, which expresses two meanings: First, human nature is evil. Second, people can get better through acquired education. Xunzi believes that the good fortune and bad fortune in the world are produced by people's own control and adjustment, not by "heaven". As the saying goes, there is heaven on earth and mortals on earth. What people have to do is to distinguish between people and justice.

He was a famous thinker, philosopher and educator in the pre-Qin period, a representative of Confucian school and a master of a hundred schools of thought contending. Xunzi also sorted out and passed on Confucian classics such as The Book of Songs, Shangshu, Li, Yue, Yi and Chunqiu, and made great contributions to the spread and preservation of Confucian ideology and culture.

In his later years, he lived in Lanling County, wrote a book saying that he was taught by his disciples and died in Sri Lanka, which was called "Housheng". Xunzi critically accepted and creatively developed Confucian orthodoxy and theory, and advocated "both etiquette and law"; Put forward the view that people who "master their destiny and use it" will conquer nature; Oppose superstition of ghosts and gods; Put forward the theory of evil nature, attach importance to the influence of customs and education on people, and emphasize the application of what you have learned; His thoughts are reflected in Xunzi.
