ZHE WANG

But in this vast land, Wu dialects have many divisions and changes, and even people can't understand what is said in a village a hundred meters away. (The main body of this language is mainly in the Taihu Lake area of Jiangsu and Zhejiang. The language is like the rhizome of a big tree and the spread of a river, which will continue to evolve and expand)
The main reasons are as follows:
1. Many immigrants and mixed cultures
2. Due to the special topography and geomorphology of this area, there are many mountains and hills. In ancient times, it was difficult to communicate with each other due to inconvenient transportation.
3. The rivers in this area are short and the population that gathers along the banks is limited
4. Lack of unified government regulation and management
