Why did Ming Zuling choose Xuyi, Jiangsu? Zhu Yuanzhang's hometown is Fengyang, Anhui. Why did he set Zuling in Jiangsu?

Because his hometown used to be Jurong County, Jiangsu Province, he searched for gold there. Because he couldn't stand the oppression of the Yuan government, his family later moved to the Huaihe River. Which is now Xuyi County. Only later did his family move to Fengyang, Anhui. Maybe his parents, maybe his grandparents moved there.

Just like some people's ancestral home was in Guangzhou, and later their father or grandfather went to Shanghai for development. He was born in Shanghai and became a Shanghainese, but his ancestral home is still in Guangzhou.
