Xunzi (about 307 BC-2 BC13 years), also known as Xun Qing and Sun Qing, was a famous educator and writer in the late Eastern Han Dynasty. He, Mencius and Confucius are also called the three important roles of Confucian culture in the pre-Qin period. He has many disciples, including Han Fei, Zhang Yi and Fu. Xunzi period was the most intense period of hegemony among Chu, Yan, Han, Zhao, Wei, Qi and Qin, and it was a turbulent period in which China feudal society gradually advanced in China and then entered a high stage of rapid transformation. In Xunzi's view, heaven is a nature without faith and purpose, and has its own operating rules. It is not based on personal will. The disorder of social development and the rise and fall of a country have nothing to do with heaven, but are caused by politics and metallurgy.

Therefore, Xunzi put forward the propaganda slogan of "controlling destiny and using it". He stressed that only by giving full play to my initiative and actively understanding and grasping the laws of nature can we update, transform and make good use of nature. Undoubtedly, Xunzi's incisive topic "Everything depends on human effort" has a milestone significance in the history of China's philosophy. Xunzi belongs to Confucianism and has a certain development trend to Confucian culture. In philosophy, he put forward the problem of "everything depends on people" and wanted to "master fate and make use of it". He holds the theory of "evil nature" and pays attention to the importance of learning, training and loyalty. In political thought, Wang Ba thought that ethics should be combined with morality. Xunzi's lyric poems grew up in criticism, with rigorous exposition and simple style.

He also wrote a "Xiang Xiang Ci" and a "Fu Pian" in the form of Chu Ci, which played a leading role in the creation of Fu. Xunzi belongs to Confucianism, but is close to Legalism. Han Feizi and Qin Xiang Zhang Yi, famous legalists in the Eastern Han Dynasty, were his apprentices. Obviously, his legalist thought has made great academic achievements. In the history of China after Qin Dynasty, Legalists were treated and selected by the rulers and Confucianism in parallel, while Confucianism was used externally. In Confucian culture, Xunzi advocated inherent vice, which is contrary to Confucius' good nature and has certain practical significance and different positions. But on the whole, they are hostile to Confucius school, and they think it is appropriate respectively. Confucius advocated benevolence, while Mencius and Xunzi emphasized ethics, which caused great harm to future generations. Among them, its jurisprudence did great harm to later generations, and it was introduced into the late Qing Dynasty by direct current.

Generally speaking, in the classification of Confucian scientific research, Xunzi is usually classified as a representative of Confucianism. Xunzi's ideas can be used for reference in many fields other than Confucianism, that is, politics and metallurgy of Confucian culture. Xunzi's idea is precisely aimed at the basic national conditions that turned upside down at the end of the Warring States Period, understanding and carrying forward Confucian rhetoric in a pioneering and innovative way, and just shows the potential versatility of Confucian learning kings. Later Confucian scholars will definitely mention the concept of Xunzi when talking about the time of Confucian scholars.
