Brief introduction of Jiangsu dialect:

Jiangsu spans the Yangtze River and Huaihe River, with obvious differences in regional culture and dialect culture.

In fact, there is no such thing as "Jiangsu dialect". Jiangsu Province is divided into three dialect areas, namely Jianghuai Mandarin Area, Wuyu Area and Zhongyuan Mandarin Area. Various dialect areas can communicate with each other, for example, cities in Wuyu area can communicate with each other in dialects, but there is no communication between cities in Wuyu area and cities in Jianghuai Mandarin area.
