What are the strategies for the three-and-a-half-day journey from Chengdu to Seda via xinduqiao?

When you take a bus at Chengdu Chadianzi Station, you need to buy a ticket one or two days in advance. You leave at 6: 20 in the morning and arrive at Seda around 20: 00-2 1: 30. The ticket is between 220 and 250. The bus will stop at Sedafo College Station, change to the bus, which runs every hour at/kloc-0, and you can choose to walk up. It is recommended to stay at the Laron Hotel, which is the highest point of the whole Sedafo College. The next morning, you can go to Sedafo College for morning classes and go down the mountain by car. If you are in the county seat, you can stay in the county seat for one day. It is recommended to stay in Seda for at least three days. The next day, I went to Sedafo College. There is a through train in the county. On the third day, I went to the celestial burial platform and could carpool with others.
