How many nationalities are there in the northeast of China?

I know what you mean. For example, there are several Tibetans doing business in Harbin, which is definitely not included by you.

There are 12 aborigines in Northeast China:

Manchu, (needless to say, the northeast itself is called Manchuria)

Han nationality, (mostly immigrants after the middle and late Qing Dynasty, mainly from Shandong and Hebei)

Mongolian, (mainly distributed in the western part of the three northeastern provinces, mostly formed by grazing land in Horqin)

Xibo nationality, (a branch of Manchu, originally belonged to Horqin Department of Mongolia, and most of them moved to Shenyang, Shuangcheng and other cities after being merged into the Eight Banners)

Oroqen nationality, (mainly distributed in western Heilongjiang and Daxinganling area)

The Daur nationality (together with the Oroqen and Ewenki nationalities, it was once collectively called the Soren tribe, and lived with the Mongols for a long time, most of which were incorporated into the Eight Banners).

Ewenki nationality, (basically similar to Oroqen nationality)

Kirgiz nationality (originally a Central Asian nationality, living in southern Xinjiang, part of which was merged into the Eight Banners during the Qianlong period, and then moved to Heilongjiang to settle down)

Hui people, (needless to say, Hui people live all over the country)

Korean nationality, (mainly due to the Korean War at the end of 19, a large number of victims fled to the northeast of China, forming a large residence, living around major cities in the northeast).

Hezhe nationality (mainly living in the eastern part of Heilongjiang and Wusuli River), like Manchu, is a jurchen, and the original tribe is Jurchen Huerha Department and Fayeko Department. ).

Russians, (a small number, some immigrants in the border areas are of Russian origin, but they are all mixed-race, and their hukou is also Han nationality, so it goes without saying that they are close relatives).
