Wujin District, formerly a separate county, is now a district of Changzhou, but it is also the largest district (although some places are allocated to other districts). The industry is developing very well, and many rich people in Changzhou are from Wujin. At that time, it was Wujin county, Changzhou city was completely surrounded, and later it was half surrounded by Wujin city. Later, in Chengwu District, many places were occupied by other four districts. Even so, Wujin is the administrative region with the largest area and the largest GDP in Changzhou, and is famous for its strong private enterprises. The inland river network in the area is dense and the natural environment is superior. Changzhou University Town is located here, which is the only administrative district that can compete with the central city of Changzhou. However, the infrastructure construction of the central area (Hutang area) is a bit backward, and its popularity and cohesion are not as good as that of Changzhou central city.
