Chi surname, pronounced Chí, has multiple surnames. The late surname of the Han nationality comes from the son of Lu, a sage of Shang Dynasty, and a disciple of Confucius. The late surnames of other nationalities come from Wei Chi and An Chi of Xianbei nationality, and Chi Jia of Manchu and Mongolian nationality.

There are three sources of delay:

1, from the descendants of the late Shang Shengxian, with the late surname.

3. The surname of the old Manchu changed from that of the old Manchu to that of China: Chi Jia, Chi Jia, etc.
