Wu dialect range?

Wu dialect is the second most spoken dialect in Chinese, but its geographical distribution is not very wide. In the south of Jiangsu, except Nanjing, Zhenjiang (Danyang, Gaochun or Wu dialect), Jingjiang, Haimen, Qidong, Tongzhou, Shanghai, Shangrao, Jiangxi, northern Pucheng, Fujian and Zhejiang, except Chun 'an, Jiande, Cangnan and Pingyang, Wu dialect is basically spoken. Xuanwu dialect is widely used in Tongling and Taiping in northern Anhui, but Jianghuai Mandarin is widely used by local people, and Wu dialect is only used within the family. Xuanwu dialect is seriously infiltrated by Mandarin. The total distribution area of Wu dialect is about 654.38+037.5 thousand square kilometers. This picture is clearly marked.
