Isn't Zhangjiakou Chengde always short of water? Why do you grow rice?

Chengde and Zhangjiakou only have less rainfall, but this does not mean water shortage.

Let me talk about Chengde first. Chengde's original ecological environment is the best in Hebei and even the whole North China, and its water reserves are also the largest in Hebei. Many rivers in North China originate in Chengde.

Zhangjiakou gives people the feeling that it is dry. Indeed, the rivers in Zhangjiakou have shrunk severely in recent years, and the largest Yanghe and Sanggan rivers are not much different from the current "streams". However, due to its special geographical location, Zhangjiakou is rich in groundwater resources, and the drinking water of ordinary people is collected from underground high-quality water by waterworks. This is the envy of many areas, and the tap water in general cities is basically river water or reservoir water.
