Those tourist attractions in Shaanxi Province will come back in two days.

If it is mountaineering: Huashan Mountain, Taibai Mountain Suzaku Forest Park, etc.

If you are going to scenic spots with strong historical and cultural atmosphere, such as Huaqing Pool and Terracotta Warriors.

If you want to have good scenery, it is natural scenery such as red river valley and Niubeiliang.

I suggest you go to the Shaanxi channel of Phoenix Network. They will recommend several interesting local scenic spots in Shaanxi every week, which should be helpful to you.
