I want to travel from Weihai, Shandong Province to Xi 'an, Chengdu, Chongqing and Kunming in summer vacation. Which is better, self-driving or self-driving?

Sichuan and Chongqing are originally mountainous areas. It's already very tiring to drive all the way from Shandong. It's not necessary to drive all kinds of mountain roads so hard. Since it's a tour, relax, take the bullet train, have a drink, eat something and talk and laugh along the way. The bullet train should take several hours to get to Xi 'an now. Chengdu and Chongqing may have to change trains.

There is a lot of public transportation in the destination. If you want to rent a car to entertain yourself, such a group of people is just right.
