From Emei Mountain to Wutai Mountain and then to Putuo Mountain, the premise is to start from Tongcheng. How to get there?

First of all, these three mountains span three provinces. I only know a little about Mount Emei. Also, sorry, I don't know where Tongcheng is. Therefore, my answer is very incomplete. But I can only tell you that if you want to go to Emei Mountain, you need to take the shuttle bus to Emei Mountain at Chengdu Xinnanmen Tourism Distribution Center and take two and a half hours to Emei Jiuzhu Passenger Transport Center. Then, you can take the 1 bus to Foguang Square, and then transfer to the No.5 bus to get off at the Guobao Temple Scenic Area Passenger Transport Center. After that, you can take the scenic sightseeing bus to Mount Emei at the scenic passenger transport center.
