If you have mountain people you know, no problem, they can lead the way and drive the car to the houses on the mountain. If you don't know each other, then either park your car in the parking lot at the foot of the mountain and take a shuttle bus to the hotel. Or when there are too many cars and roads, one or two private cars will be allowed to take luggage up. As for the section from the hotel to Tianchi, there is also a shuttle bus.
