The economic situation of Yungang should be said to be good. The residents there are basically employees of the Third Hospital of the Ministry of Space and power plants, as well as factories 159 and 6 18. There are Wumart, Hengyuan and some small supermarkets. I don't know what you mean by economy. What do you want to invest or do? If you don't know, ask, or take a look by car (buses 32 1, 339, 917,958 have all arrived, driving from Liuliqiao to Beijing-Shijiazhuang Expressway, passing Dujiakan toll station and Zhaoxindian exit, with road signs all the way west).
