Liu's early development was mainly in the north.

More than 300 years BC, Liu began to spread to Henan, Jiangsu and other places. During the Warring States Period, there was a doctor named Liu, whose descendants lived in the State of Qin. At the end of the Warring States Period, the State of Qin destroyed the State of Wei, and the Liu family followed Qin Jun into the capital beam of Wei, which is now Kaifeng, Henan. His tenth grandson worked in Wei, and moved to Daliang after the demise of Wei, and his son Liu Qing moved to today's Jiangsu and other places.

The Han Dynasty was the heyday and development period of Liu's surname. After the establishment of the Western Han Dynasty by Emperor Gaozu Liu Bang, his surname was enfeoffed in various places, and later tribes multiplied, so Pengcheng, Weishi, Linhuai, Nanyang, Guangping, Danyang and other places had Liu's surname.

In the early years of the Western Han Dynasty, there were more than 30 emperors and more than 400 marquis. Because the Han royal family was given the same surname, Liu's nobles spread all over the country and soon became powerful families everywhere.

In short, Liu is mainly from the royal family. After more than 400 years of reproduction and development, the population soared and became the first surname in the world at that time. But Liu's population is still mainly distributed in the Yellow River valley, mainly in Henan, Hebei, Shandong, northern Jiangsu, northern Anhui and Taiyuan, Shanxi. In addition, there are Liu aristocratic families in Jingxiang, Hubei, Changsha, Hunan and Jiujiang, Jiangxi.

At the end of the Han Dynasty and the Three Kingdoms, Wei Liu in the Central Plains kept migrating in all directions, mainly to Sun Wu in the southeast and Sichuan in the southwest.

During the Wei, Jin, Southern and Northern Dynasties, the central and northern regions fell into war again. Like other surnames, Liu in the Central Plains moved to the south, southeast and southwest to escape the war, and some moved to Japan and the Korean Peninsula. From the Eastern Jin Dynasty to the Tang Dynasty, the migration of the Central Plains to the south and southeast regions never stopped, and the migration became larger and larger, and the region became farther and farther.
