What is the gap you are talking about? Geographically, there are many mountains in Guizhou, which is more difficult than the hills in Sichuan. Chengdu is in the small plain in the middle of the basin, and Guiyang is still in the mountainous area. Economically speaking, Chengdu is also much more developed than Guiyang. Chengdu can be said to be the center of the whole southwest, including the military region. In this respect, there is a big gap.
