Because it was to go to Ya'an Base to see the giant panda, Ya'an Base was in Bifengxia Scenic Area, and could only buy tickets for Bifengxia Scenic Area. Because I only went to see the giant panda, the canyon and elevator in the ticket were not used, I don't know what the situation is; Anyway, Ya'an Base is very satisfied with the panda, that is, the sightseeing bus needs to wait for people to basically sit full before leaving, and the time is uncertain.
