Zhongwei, Gannan, Jiuzhaigou, Chengdu, Xi'an self-driving tour, such a route design is not reasonable

It's okay. However, some routes are not necessarily easy to follow.

Overall, it's okay! From Chengdu to Xi'an, you can also consider it...

Generally speaking, it's okay, but Xi'an is relatively far away. Generally speaking, Jiuzhaigou in Chengdu and Chongqing is a line. There are too many areas involved and it may not be possible to play well within a limited time. Please consider carefully when traveling

Very good, you can go shopping.

I think it's okay. I suggest that when you go from Chengdu to Xi'an, you can visit places such as Hanzhong and Qinling, and take a walk along the Shu Road.
