I want to travel by car from Xi'an-Gannan-Chengdu for 7 days

The scenic spots in Gannan include Zhuoni Dayu Valley; Xiahe Labrang Monastery, Sangke Grassland; Luqugahai, Zecha Stone Forest, Langmusi; Maqu Grassland, and the first bay of the Yellow River's nine bends; Lintan Yeliguan; Cooperate with Mirangri Bar Buddhist Pavilion and so on. The scenery is most beautiful in August. Accommodation is not expensive either. You can stay in a pretty good hotel for more than 100 yuan. Accommodation is also very convenient, and there are places to stay in various scenic spots. If you don’t want to live there, you can live in the county. Chengdu Wuhou Temple, Jinli, Du Fu Thatched Cottage, Panda Base, Dujiangyan, etc. The accommodation is quite good. From Gannan to Chengdu, you will take the Songpan-Wenchuan line. The road is more dangerous and mostly rocky. However, the Ruoergai grassland after leaving Langmusi is very beautiful, and Songpan is also very unique. However, the accommodation in Songpan is very expensive and the facilities are not good. I hope I can help you
