Why is there such a big sandstorm in spring in Wuwei? What caused it?

The main reason is the lack of water in northwest China in recent years, the uncontrolled exploitation of natural resources by human beings, the indiscriminate cutting of valves and the destruction of a large number of vegetation. In addition, a series of reasons, such as spring breeze and Wuwei's proximity to Tengger Desert, led to a big sandstorm in Wuwei in spring, but now Wuwei is controlling sandstorms, which is much better than in previous years. As a Wuwei person, I can't watch my mother being swallowed up by the wind and sand. Let's take action to build our home together and make our mother younger and more beautiful!
