My surname is Jiang, Manchu, from Chifeng, Inner Mongolia. I want to know my last name and which of the Eight Banners.

Originated from Jurchen nationality, it belongs to sinicization and changed its surname to surname. According to the historical book A Brief History of Tongzhi Clans in Qing Dynasty and Manchu Eight Banners' Surnames, the Manchu Jiang Jiashi, whose Manchu language is Jiyang Jihala, was originally a Han nationality, and was taken by the Wuhuan Department of Xianbei in Liaodong at the end of the Eastern Han Dynasty, and then gradually evolved into a jurchen in Liaodong, living in Ningguta (now Ning 'an, Heilongjiang Province) and Xingshan (now Jinzhou South, Liaoning Province) and belonging to Manchuria, a Huang Zhengqi.
