What should I do if there is no one in the Ming Dynasty?

This question is really a bit general.

At the beginning of the Ming Dynasty, the Central Plains (Lu Yu and Hebei) was sparsely populated due to years of wars and floods in the Yellow River basin at the end of the Yuan Dynasty, so Ming Taizu adopted an immigration policy and moved in according to the proportion of "one family of four, one family of six, two families of eight and three families of eight". Mainly from Shanxi and Jiangsu and Zhejiang provinces. Ming Chengzu wanted to move the capital to Beiping, so he immigrated from Shanxi and the rich areas in the south to fill the population near Beiping. The household registration policy in the early Ming Dynasty was strict. If you want to go from one city to another, you need roads, and then you must come back. But by the middle of the Ming Dynasty, the system was not strict, and no one implemented it, which led to population mobility. However, China people have always had the habit of going to big cities, so most cities should be short of people, except for the large number of refugees in the late Ming Dynasty, which may affect the urban population.
