Do people in southern Anhui, Xuancheng and Huizhou also speak the Wu dialect of Suzhou dialect and Shanghai dialect? Why is there Wenzhou dialect in southern Anhui?

As a prefecture-level city, Xuancheng dialect is still quite complicated. Generally speaking, there is Wu dialect in Xuancheng, but most of it is not a small piece of Suzhou dialect in Shanghai dialect: Taihu dialect is in Suzhou and Shanghai, Xuanwu dialect is mostly in Xuancheng, and several towns bordering Yixing and Liyang are all Taihu dialect. However, there are not many people who use Wu dialect in Xuancheng now, mainly because the Taiping Heavenly Kingdom caused a heavy blow to the indigenous population, and then immigrants moved in one after another, accounting for the majority of the population. At present, the dialects in Xuancheng are mainly Jianghuai Mandarin (close to the accents of neighboring Wuhu and Nanjing), and some dialects brought by early immigrants (such as Hubei dialect). Wu dialect has declined and retired to the countryside, with fewer and fewer young people. Huizhou dialect (mainly reflected in Huangshan City) is widely used in Huizhou, and foreigners can hardly understand it. Due to the topography of Huizhou, dialect preservation is better than other surrounding areas. As for Wenzhou dialect, my grandfather's grandfather is from Wenzhou. When he was young, his family moved to Xuancheng. My grandfather can still speak Wenzhou dialect, but it is seldom said that my mother's generation can't. I think it may be the cause of population migration.
