My father is going to work in Ningxia. What is the weather like there, especially the temperature?

That depends on where you go to work in Ningxia, where the climate is very different.

Ningxia is located in the northwest inland plateau, with a continental semi-humid and semi-arid climate. Winter is long, summer is short, rain and snow are scarce, the climate is dry, and there are more sandstorms. Yinchuan, the capital, has abundant surface water and slightly humid air. May-10 is the best season every year, and you can bring sand-proof articles such as hats and sunglasses before winter.
