It's really shocking. If there is a tour guide or can keep up with the explanation, it is another experience. If you can, it is really recommended to bring a guide. In addition, you can save the package at the door, and you have to save the package and go there, otherwise it will be tired enough to go through the backpack in a day. I met other guides in the next few days. When I went to the desert to pass by Shuangling + Helan Mountain, I felt really different. (The suggestion that you like to take pictures and punch in is in the corridor at the door, it is beautiful)
