Hongwu's expulsion was a large-scale immigration activity in China in the early Ming Dynasty. In order to develop agriculture and strengthen the rule of frontier areas, Zhu Yuanzhang, the founding emperor of the Ming Dynasty, moved a large number of people into new areas to settle down. Many families in Suzhou have moved to northern Jiangsu, including Yangzhou and Taizhou.
According to the genealogy of the Xu family in northern Jiangsu, the ancestors of the Xu family in northern Jiangsu moved from Nagato in Suzhou to Baoying in Jiangsu during the Hongwu period of the Ming Dynasty. This genealogy also records in detail the lineage inheritance and important figures of the family since the Ming Dynasty, which provides valuable information for future generations to understand the family history.
Therefore, according to historical records and genealogy records, it is indeed possible for the Xu family in northern Jiangsu to move from Nagato in Suzhou to Baoying in Yangzhou during the Hongwu period of Daming.
