Is such a self-help tour in Guangxi and Yunnan feasible in May? Will it be too hard?

this trip is to arrange for you to play by car, which is worthy of the name. It's too hard for the elderly, and it's simply suffering (young people may not be able to eat it). Retirement time should be very generous, and it is recommended to travel directly from point to point, which is easy and easy to travel. As long as you avoid the golden week and the peak of travel in winter and summer vacations, the discount on air tickets is much lower than that by car.
