1. There are two sources of Jia's family:

1. From Ji's surname, after Jia Bo. According to Yuan He's Surname Code and the New Tang Book Prime Minister's Hereditary Table, in the Western Zhou Dynasty, Tang Shuyu, Zhou Chengwang's younger brother, was sealed in the Tang Dynasty after the Duke of Zhou destroyed the Tang Dynasty (now the west of Shanxi's wing), including the former capital area of Xia Dynasty (now the north of Xia County, Shanxi), and was awarded nine cases of Huai surname. Since then, Tang Shuyu has become the ancestor of many surnames such as Tang, He, Yang, Wen and Han. After Xie ascended the throne, it was renamed the marquis of Jin, which was the state of Jin. Shortly after the Duke of Zhou enfeoffed Tang Shuyu in the Tang Dynasty, Tang Shuyu's youngest son, Gong Ming, was named Jia (now southwest of Xiangfen, Shanxi Province) by the son of King Kang, nominally a vassal of the Tang State, with the number Jia Bo. In the Spring and Autumn Period, Jia was destroyed by Jin, and the descendants of Jia Bo Gongming took the country as their surname, which was called Jia's, because it was Jia's in Shanxi.

2. After Huyan. According to Textual Research on Surnames, in the Spring and Autumn Period, after Jin Wengong and Zhong Er destroyed Jia, Duke Xiang of Jin gave Jia land to Fox Shooting, the son of Hu Yan who helped Jin Wengong dominate. He is also called Jia Ji and Jia Ta. After Xiang Gong's death, there was a fight over which brother of Li Xiang Gong was the king. Jia Ji fled to Zhai Guo to avoid disaster, and his descendants took Jia as their surname and called him Jia.

Second, the migration and distribution of Jia originated in Shanxi Province. During the pre-Qin period, some people moved to Henan and Shandong. Since then, the Jia family in Henan has prospered, and the population has flourished, and many tribes have been derived. For example, Jia Yi, a political commentator and writer in the Western Han Dynasty, was from Henan. During the Han Dynasty, Jia moved to Shaanxi. For example, Jia Hui, a native of Ping Ling (now northwest of Xianyang, Shaanxi) in the Eastern Han Dynasty, is said to be a descendant of Jia Yi. During the Northern and Southern Dynasties, Jia continued to move out. In the Northern Zhou Dynasty and the Northern Qi Dynasty, Jia people moved to Hebei. At the latest in the Eastern Jin Dynasty, there were Jia people who crossed the river south and lived in Jiangsu and Zhejiang provinces. In the Five Dynasties, Jia moved to Fujian, and in the Song Dynasty, some people moved to Sichuan. It can be seen that during the Tang and Song Dynasties, there were Jia residents in many places in the south of the Yangtze River. Jia's emigration began in the Qing dynasty, and now there are overseas Chinese named Jia in Singapore and other countries.

III.No. of County Lookout Hall

County Lookout Wuwei County: In the second year of the inaugural ceremony of the Han Dynasty (121 BC), the county was established in Wuwei (now the northeast of Minqin, Gansu).

When the Eastern Han Dynasty moved to the sixteen countries of Guzang (now Wuwei, Gansu), the former cool, the latter cool, the southern cool and the northern cool were all built here.

The name of the hall is Zhiyantang: In the Han Dynasty, Jia Shan read a lot of books, told the court about the way to control chaos, and used the demise of Qin as a metaphor. It was called Zhiyantang. In addition, there is "Wuwei Hall"

During the reign of Emperor Zong, the power was more powerful, and the appointment of a surname and the peace of the military were important.
