Why is Ebinur Lake not allowed to travel?

The reason why Ebinur Lake is not allowed to travel is that Ebinur Lake is one of the four sources of sandstorms in China, which is not suitable for human life. Ebinur Lake has played a great role in resisting sandstorms and protecting railways, just like an umbrella to maintain the ecological balance of this area and even the whole northern Xinjiang. However, in recent years, due to the shrinking area of Ebinur Lake, when strong winds sweep the dry bottom of the lake, tiny salt dust and sand grains will be rolled up, forming a sandstorm all over the sky.
