I plan to travel to Jiuzhaigou by car on August 9th, but the weather forecast now predicts heavy rains in Wenchuan and Mianyang areas. Is it dangerous to take a car?

I just came back from here. If you are taking a plane, bring long pants, a short-sleeved jacket, and an umbrella, because it can be cloudy and rainy suddenly.

If you are taking a plane, After the train, you need to bring more clothes when you take the bus and pass by Chuanzhu Temple. It is only a few degrees there and it is extremely cold. The Tibetans there are already wearing back-back Tibetan robes...
