If you take the bus, take the light rail to four kilometers first, then you can see the four-kilometer hub station when you leave the station, where you can take the bus to Fengdu, and you can see the ghost town when you get to Fengdu Station. After getting off the bus, you can take the bus (it's easy to sit in the morning, but it's long after noon) or go to the ghost town by boat. It is recommended to take a bus to the dock at the station, and the starting price is ok. Take a boat to the dock to cross the river, and it will be a ghost town.
There is only one famous cave in Fengdu. If you want to go, take the bus passing through the snow cave at the station where you just got off and get off at the station.
If you have a student ID card and other documents, it is recommended to carry them with you. Both scenic spots can be discounted.
