Compared with Chongqing and Lanzhou, which city has more room for development?

Personally, I think it’s Chongqing

Chongqing is a municipality directly under the Central Government, and the government’s policy support for municipalities is relatively tilted. Moreover, Chongqing has developed very rapidly in the ten years since it was directly under the Central Government, putting Chengdu and Xi’an to shame. In addition, Chongqing has better geographical advantages, being located in the upper reaches of the Yangtze River and a port hub.

The railway is also constantly improving

Lanzhou is in the northwest. First of all, water shortage is a bottleneck restricting Lanzhou's development. Water shortage has a great impact on industry. In addition, Xi'an's position as the largest in the northwest also restricts Lanzhou's development. However, Lanzhou is located in The intersection of Longhai-Lanzhou-Xinjiang Line and Qinghai-Tibet Line is still helpful to tourism and foreign trade exports
