Why can Tongling build a city?

This mainly depends on Tongling's unique resource advantages, and it is also a manifestation of the national recognition of Tongling's strategic significance. Just look at several resource cities in Anhui. Ma 'anshan, Tongling, Huainan and Huaibei are small and refined resource-based cities, all under the jurisdiction of one city and one county, and they all have decisive resources or energy in their respective industries in China. In addition, Tongling is a city along the Yangtze River and the middle section of the trunk line (Beijing-Taiwan Expressway) that runs through the north and south of Anhui. Tongling Yangtze River Bridge is the first bridge in Wanjiang, many years earlier than Wuhu Yangtze River Bridge.
