Who knows when the Ming Dynasty was or whether many Nanjing people moved to Yunnan?

In the Ming Dynasty, more than 800,000 people moved from Jiangsu and Zhejiang to Yunnan, and almost all the Han people living in Nanjing were evacuated. Manchu entered the customs, engaged in massacres in Jiangsu and Zhejiang, and a large number of Han Chinese were exiled to Yunnan. Nowadays, people in Jiangsu and Zhejiang provinces are mostly descendants of Jiangsu and Zhejiang provinces. Almost all the original Han people in Jiangsu and Zhejiang have become Han people in Yunnan, while most of the modern Han people in Yunnan are descendants of the original Han people in Jiangsu and Zhejiang.
