Han Fei (about 280- 233 BC), South Korea at the end of the Warring States Period (now Xinzheng, Henan, belonging to Zhengzhou; Zheng Han, a Han nationality in Xinzheng, Henan Province, is a famous philosopher, thinker, essayist and legalist in ancient China. He is known as "Han Feizi" in the world. Han Fei was originally a North Korean aristocrat, who followed Gou Jian with Li Sishi. Han Fei stuttered, but he was good at writing. He inherited and developed Xunzi's magical thought. At the same time, he absorbed his previous legalist theory, compared the gains and losses of political reform in various countries, and put forward the theory of "emphasizing law" and combining law, technique and potential, which is a great achievement of legalist thought.

Han Fei wrote to the king of Korea many times, asking him to reform strongly, but it didn't work. Instead, he got angry and wrote a book for Wenda. The king of Qin admired his name, and Han's suicide note invited him to the State of Qin. Han Fei's thoughts were reused by Qin Shihuang. His legalist theory provided a theoretical basis for the birth of the first unified and autocratic centralized state in China. Han Fei was falsely injured by Reese and Yao Jia in Qin State and died in prison. There are fifty-five articles by Han Feizi today.

There are many books written by Han Feizi, but they are all included in the book Han Feizi. There are 55 books in this book. What is important is Han Feizi's theory of rule of law, which is the master of legalism at that time.

Among them, Lonely Anger discusses Han Feizi's own grief and anger; Saying that it is difficult is an analysis of the monarch's psychology, which shows the difficulty of persuading him. The first half of "Rape and Robbery of Officials" is about specific methods to punish corrupt officials, while the second half is about opposing Confucianism and advocating legalism. Xian Xue is the representative work of Han Feizi's thoughts on the rule of law and the main historical source of China's thoughts on ancient studies. There are also five kinds of people who disturb the king's rule of law, which Han Feizi thinks should be eliminated. Han Feizi thinks to be a scholar, an empty talker, a sword bearer, a victim of an empire, a businessman and so on. It is a moth among the five moths.

Han Feizi was a rare talent in the Warring States period, and he had his own views on history and future. When Han Feizi realized the chaos of his country's economy and social order, he put forward "the people are rich but the goods are scarce", which shows that Han Feizi's thought is transcendent and was written before his death. Many literary works have been handed down to this day. Unfortunately, he was born in Korea and died in Qin.
