Han Fei (about 280 BC - 233 BC) was a Korean nobleman at the end of the Warring States Period and a master of Legalist thought. He studied under Xunzi and was a classmate with Li Si. Although he stutters, he is good at writing and his articles are powerful. The core of his ideology advocates the theory of monarchy that combines "law, technique, and power", proposes "rule of law" to replace "rule of man", and emphasizes that "the ministers will not be spared in punishment, and the good will be rewarded". He is the author of fifty-five chapters of "Han Feizi", among which "Gu Anger", "Five Worms" and "Shuo Nan" are particularly famous. Although Han Fei was not reused in Korea, his ideas were adopted by Qin Shihuang and became the governing philosophy of the Qin Dynasty after its unification. Later, because of Li Si's jealousy and slander, he died unjustly in the Qin prison. His theory had a profound influence on the bureaucracy and legal system of ancient China.
