This trip is a group tour. In one day, we went straight from Chengdu to Siniangshan, which is nearly 4000 meters above sea level. It was rainy and cloudy. It was clear in the sky, green in the mountains and fresh in the air. We also bought plums and apples, which are very sweet and cheap. We took sightseeing cars in scenic spots along the way, so we won't be very tired in energy consumption. There is a period of drifting, it's interesting to see others try to drift.
