Tianjin people migrated from Anhui before?

Part of it is. Tianjin people have certain connections with Anhui people, because there were large-scale immigrants in Tianjin during the Ming Dynasty, most of whom were Anhui immigrants. These Anhui immigrants gradually settled in Tianjin and became part of the population of Tianjin today. Therefore, it can be said that some ancestors of Tianjin people migrated from Anhui.

But this does not mean that the ancestors of Tianjin people all migrated from Anhui, because the population composition of Tianjin is complex, including different immigrants and local population.
