I heard the old man say that his family used to belong to Beijing Straw Hat Hutong, and later I was sent to Jilin to know if his Manchu surname was Guarga and what flag it was.

There are nearly 700 surnames in Manchu, among which Guaer family is the most, but not all Guaer families belong to the same family. This surname consists of several families with the same surname and different clans. Some are Suwan Guaer's family, some are Baishan Guaer's family, some are Wusu Guaer's family ... and so on, very many.

What makes you think your old surname is Guarga? Did you listen to grandpa? Or did you guess it yourself?

The straw hat hutong in Beijing you mentioned was an immigrant during the Qianlong period of the Qing Dynasty. At the beginning, Manchu people lived in the northeast before entering the customs, and many people moved to Beijing after entering the customs. During the reign of Kangxi, in order to develop their hometown in the northeast, the Qing court began to move Manchu people who entered the customs back to the northeast. The largest number of immigrants was twice, one of which was in Qianlong 17. At that time, Manchu people living around Beijing were transferred back to Northeast China by households, mostly in Jilin, Lan Shu, Acheng, Fuyu, Lalin and Wuchang. At that time, the immigration agency was located in Cao Mao Hutong, wanping county, southwest of Beijing, where all immigration procedures were handled. Therefore, the Manchu people in Qi Jing who returned to the northeast today claimed to have come back from Cao Mao Hutong.
