The Three Kingdoms (220-280) is a historical period after the Han Dynasty and before the Jin Dynasty in the history of China. During this period, three major regimes emerged: Cao Wei, Shu Han and Soochow.

190, the centralization of the Han dynasty collapsed, warlords everywhere scuffled and the world was in chaos. In 2008, Battle of Red Cliffs happened, and Cao Cao was defeated by Sun and Liu Lianjun, which laid the rudiment of the tripartite confrontation among the three countries. In 220, Cao Pi, the prime minister of the Han Dynasty, forced Emperor Xian of the Han Dynasty to abdicate, making Luoyang its capital, with the title of "Wei", known as Cao Wei in history, marking the official end of the Han Dynasty. 22 1 year, Liu Bei proclaimed himself emperor, with Chengdu as its capital, which was known as Shu Han in history. In 229, the rising sun, the capital Jianye, Feng Wu, Shi said.

Controversy:

Both Chen Shou's History of the Three Kingdoms and Luo Guanzhong's Romance of the Three Kingdoms are called Wei, Shu and Wu. In fact, in Liaodong, there is a country with the same nature as Wei, Shu and Wu ── Yan State, which began to grow and develop in 190 and was destroyed by Sima Yi in 238. It has been established for 48 years, which is 6 years longer than the Shu Han established by Liu Bei. Gongsun Du, the little-known founding hero of Yan State, is also comparable to Cao Cao, Liu Bei and Sun Quan.

Xu Rong, the ministry of Gongsun Du and Dong Zhuo, is a fellow villager. On the recommendation of Xu Rong, Gongsun Du was appointed as the prefect of Liaodong. 190, Dong Zhuo coerced Emperor Xian of Han to move the capital. At this time, the Central Plains was in chaos, and Liaodong County was located in the northeast, which was less affected and was able to take the opportunity to revitalize. Soon, Gongsun Du divided Liaodong County into two counties, western Liaoning and central Liaoning, each with a satrap. He also set up an altar in the suburbs of Xiangping according to the royal regulations, and performed the ceremony of heaven and earth in the suburbs, regardless of driving, ceremony and clothing.
