Dai Manchu people want to know what flag it is!

Tongyuanbao in Fengcheng, Liaoning Province does have a full family name, and it really belongs to Huang Zhengqi. Ancestors moved from Beijing to Fengcheng to defend the border during the Kangxi period of the Qing Dynasty. Unfortunately, the information I saw didn't specify what the old surname was.

There are many sources of Manchu surnames, such as Manchu Eight Banners: Dajia, Daijia, Daitong, Wusu and Daila; Among the Eight Banners of Mongolia: Dezite and Dabrosh; The eight banners of the Han army are worn.

You can go back to your hometown and check the genealogy of your relatives. If you don't have a family tree, ask an old man with the same surname. It is easy to find out whether it is the Manchu Eight Banners, the Mongolian Eight Banners or the Han Army Eight Banners first, and then find it after sending it to a small area.
