Why did Suzhou Nagato exile the population in Ming Dynasty? Great gods, help!

Today's Yancheng people will almost tell you that their ancestral home is "Suzhou Langmen" and they came to northern Jiangsu from southern Jiangsu because of "Hongwu". This cultural phenomenon is the same as that of Shandong people who say that their ancestral home is under the pagoda tree in Hongtong County, Shanxi Province. According to Yancheng County Records, shortly after Zhu Yuanzhang ascended the throne, in order to retaliate against the support of the gentry and people in Jiangsu, Songjiang, Jiaxing, Huzhou and Hangzhou for Zhang Shicheng, 400,000 people from Wang Fu were driven to northern Jiangsu on the grounds of resettlement, leaving a historical case with different opinions. Why do hundreds of thousands of people say they are Suzhou changmen? He Lv City, the prince of Wu, built the scale of Suzhou City today. There are eight gates in Suzhou, among which the Snake Gate and Panmen symbolize the intention of conquering Yue and returning it to Wu. Qimen opposes Qi, aiming at subduing Qi. Nagato is located in the west of the city. He Lv must first break the West and strengthen Chu. Yancheng people say that their ancestors were Suzhou master, which somewhat reflects the "complex" that Hongwu's descendants hate Zhu Yuanzhang's support for Zhang Shicheng. In addition, it can't explain the historical phenomenon that hundreds of thousands of people are Nagato.
