Which city in China do you think has the best geographical location?

Geographical location is determined by geographical environment! It involves the size of the area, traffic conditions, products and other aspects. It is ridiculous to simply say which city is good without saying why! As far as Chinese mainland is concerned, Chengdu is in the southwest, Wuhan in the south-central part, Xi in the northwest, Zhengzhou in the central plains, Nanjing in the south of the Yangtze River and Shenyang in the northeast. If you add the ocean plate, there are Guangzhou in the south, Shanghai in the east and Tianjin in the north. From the perspective of world division of labor, Shanghai is the city with the best geographical position in East Asia, so it has the strongest economic strength. Some people say that the economic strength of Tokyo in Japan far exceeds that of Shanghai, which is a departure from the historical and social systems of China and Japan. The real contrast is in the 1920s and 1930s. It's just economic geography Politically, Beijing is the best city in East Asia and Northeast Asia. Needless to say, the political center of East Asia and Northeast Asia has been in Beijing for most of the time since the tenth century! ! This is only discussed in East Asia, if you add Southeast Asia, South Asia and Central Asia. The city with the best geographical location will change. As for which city, what are the reasons, and what are the reasons for the change? Limited space, not much narrative! !
