Where did the Han immigrants in Baotou go?

Baotou City is divided into three main urban areas, Kundulun District and Qingshan District. Both. Most of them are immigrants. Most of the former were migrated from Northeast China, Hebei and other places during the construction of Baotou Steel. The latter comes from the construction of state-owned units such as Factory 202, and a large part of them are migrants from Hebei. Incomplete understanding, for reference only.
