Cao Cao conquered all directions in the name of Liu Xie, the Emperor of the Han Dynasty, wiped out the separatist forces such as Er Yuan, Lu Bu, Liu Biao, Ma Chao and Han Sui at home, surrendered to Xiongnu, Wuhuan and Xianbei in the south, unified the northern part of China, expanded reclamation, built water conservancy projects, rewarded agriculture and mulberry, attached importance to handicrafts, resettled refugees and implemented "rent adjustment", which promoted the economic production and social stability in the Central Plains.

Cao Cao's Literary Achievements
Cao Cao loves tomb raiding codes and six arts. In the melee of unifying the north, we should pay attention to the protection and collection of books. In the fifth year of Jian 'an (200 years), after defeating Yuan Shao, he ordered to "collect all his books and treasures". After Gong Wei took office, he set up an official in charge of ancient books, widely collected the official and folk books of the Eastern Han Dynasty scattered in the war, and "collected them and kept them", which were hidden in the three museums and secretary provinces at home and abroad.
Cai Yong's daughter, Cai Wenji, was also invited to talk about her book collection, while Cai Wenji "wrote a book and sent it, and the text was correct". Because he attached importance to the cultural construction of the country, he gradually established the National Library of Wei State.
Cao Cao took Taiping Dao, caressed the forces of Wudou Midao, concentrated on controlling the alchemists, and even secretly fought for the "destiny" for the purpose of "holding the emperor to make the princes". The great cause of Wei Chengsheng, which Cao Cao managed all his life, was realized through Cao Pi's meditation in the first year. From the rise of Cao Cao's forces to Zen Buddhism in the late Han, Wei and Han dynasties, many major historical events are deeply related to primitive Taoism.
