What's the weather like in Inner Mongolia and Lanzhou? thank you

Hehe, I'm from Hohhot, and now I'm studying at Lanzhou Jiaotong University. The wind in Lanzhou is not as strong as that in Inner Mongolia. Sometimes there is no sun for several days and the air pollution is serious. The weather in winter is always gray, but it is warmer than that in Inner Mongolia, and the lowest temperature is MINUS 10 degrees. Generally speaking, I can adapt. You can keep asking me if you need help.
