in 256 BC, the state of Lu was destroyed by the state of Chu, and some people named Liu lived in Chu. After Qin destroyed the six countries, some people lived in Shanxi, and then they gradually formed a noble family in Hedong (now the area east of the Yellow River in Shanxi). For a long time after that, Hedong has been the development and reproduction center of Liu's surname, and many celebrities of Liu's surname are also from Hedong. The Book of the New Tang Dynasty and the Prime Minister's Lineage Table shows that at the end of the Qin Dynasty, Liu Xiahui's descendant Sun Liuan began to live in Hedong Jie (now Jiezhou Town, Yuncheng, Shanxi Province), Liu Wei, the grandson of Liu An, was Qi Xiang in the Western Han Dynasty, and Sun Liufeng, the VI, was appointed as Guang Luxun in the Eastern Han Dynasty. Sun Liugui, the sixth son of Feng Zhi, was appointed as the minister of the official department of Jin Dynasty, and his son, Liu Jingyu, was the assistant of Jin Dynasty. Jing You's son was appointed as Jin Taichang Qing and Pingyang Taishou, and Jing You's son was appointed as the post-Wei Hedong county magistrate. In addition, Liu Shilong, the general of Wuwei in Liu and Song Dynasties, was a branch of Hedong. He had five sons, all of whom were prominent officials in the Southern Dynasties: the eldest son Liu Yue, the official in the middle of the book, the second son Yu, the official to the minister, and the two brothers were equally famous. Sometimes, there was a comment that "Liu's two dragons can be described as a thousand miles a day." The third son Yun, the final official right general, the fourth son Cheng, the official prefect of Shu County, the fifth son Chen, and the official doctor Guanglu, all of whom once led the state animal husbandry. This branch of Liu's surname has a glorious and prominent trend, which can be seen.
Before the Tang Dynasty, Liu's surname had settled in Sichuan, Guangxi, Fujian and other places. After the Tang Dynasty, Liu's surname was said to be prosperous in the south and widely distributed. During the reign of Emperor Gaozong in the Tang Dynasty, Zheng Chen and Chen Yuanguang, sons from Gushi, Henan Province, entered Fujian to open Zhangzhou, accompanied by Liu Military Academy of Henan Province. In addition, Liu Gongquan, a native of Jingzhao Huayuan (now Yaoxian County, Shaanxi Province), was a calligrapher of a generation, and was named Duke of Hedong County. Together with his brother Liu Gongchuo (then the official department minister) and his nephew Liu Zhongying, they were called "three outstanding men in one door" and Liu's family was honored.
during the song, yuan, Ming and Qing dynasties, Liu's name was mostly found in Jiangsu, Anhui, Zhejiang, Fujian and other places in the south, and Liu's surname was mostly silent in the north. Therefore, it is self-evident that Liu's surname was prosperous in the south. In the Ming Dynasty, Liu's surname, as one of the surnames of the immigrants of Sophora japonica, was moved to Shandong, Hebei, Henan and other places. In the Qing Dynasty, Liu's surname, who lived in Fujian and Guangdong, moved to Taiwan and Singapore.
Today, Liu surnames are mostly in Shandong, Sichuan, Hubei, Hunan and other provinces. At present, Liu's population ranks 5,47th in China. The population is small, accounting for about .1% of the Han population in China.
