The mountains around Lanzhou are usually bare and green is rarely seen. There is one place, however, that is very special. This place is only 60 kilometers away from Lanzhou, on the edge of Yuzhong County Town, which is Xinglongshan National Nature Forest Reserve. The climate of Xinglong Mountain is quite special. When it is surrounded by sunny skies, when it enters the mountain, it will often rain, and only within the scope of the mountain. So it's interesting.
