Ctrip booking is very convenient, the door can be swiped, the ice waterfall inside is really beautiful, that is, most of the scenic spots are closed in winter, only part of it is open. Just walked a little tired and it was over. 2 hours back and forth is enough. Only there is a bathroom at the door (the only open), and the bathroom above is closed! Be sure to pay attention to this! If it is an elderly person, it is a bit laborious, there are too many steps, and there are free tickets for more than 70 years old.
