Is the Han nationality in Yunnan half a Nanjing person?

Not from Nanjing. There are obvious cultural differences between Han people in Yunnan and Nanjing people, and their historical backgrounds are also different. Yunnan Han people come from several Han tribes in the Michigan River valley, while Nanjing people are Han immigrants who immigrated to the south of the Yangtze River after the Qing Dynasty and have unique culture and customs. Yunnan generally refers to Yunnan Province. Yunnan Province, called Yun or Dian for short, is one of the 23 provinces in China, located in the southwest of China, with Kunming as its capital.
