Where is Su Beiren from? Will there be Su Beiren in southern Jiangsu?

Northern Jiangsu is a kind of blood. There is no doubt that anyone who speaks Jianghuai Mandarin is of northern Jiangsu descent. Geographical Subei and humanistic Subei are the same concept. According to textual research, Jiangnan was a Wu-speaking area before the Eastern Jin Dynasty, and there were more than 900,000 northern immigrants in the late Western Jin Dynasty, far exceeding the indigenous people who spoke Wu in Ningzhen area. After several generations of development, Ningzhen area has gradually changed from a pure Wu dialect area to a Jianghuai mandarin area. Ningzhen area is the embedding area of Jianghuai Mandarin in the south of the Yangtze River. In the eyes of people in the Wu dialect area in the south of the Yangtze River, people who speak Jianghuai Mandarin belong to Su Beiren.
