Did anyone immigrate from Henan to Shandong during the Ming Dynasty?

Yes, but the main immigrants are from Hebei, and some are from Henan and Yunnan. The war at the end of Yuan Dynasty and the "Jingnan Battle" were the main battlefields in Shandong. Long-term war has caused the population of Shandong to drop sharply, thousands of miles away, and it is desolate. As a result, in the process of economic development in the early Ming Dynasty, there was a large-scale population migration. Shandong province has always been an underdeveloped area in history, and almost all immigrants are farmers. After the migration, a huge village was formed, and the migration time was probably in the early Ming Dynasty, Yongle and Hongwu years. In fact, to put it bluntly, some people moved in from other places, but the number of immigrants to Shandong is very large, which will cause a sharp increase in Shandong's population for a period of time. We must know that Shandong's population is among the best in the country now. In fact, some people on the Internet say that Zhu Yuanzhang killed a cave, but as far as I know, this situation is not true according to historical records. The main reason for the population decline in Shandong was the perennial war, and Shandong was the main battlefield, so people would inevitably suffer from the war. Therefore, the population decline in Shandong at that time was caused by the outbreak of war, people's deaths and injuries, and a large number of population movements.
