Arrived at 9:30, there was a young lady at the door who explained. She was very anxious. A total of two floors were gone. Trip.com bought a ticket for 30 yuan cheaper than the attractions. It was 10 yuan cheaper than the ticket collection place and the museum. But fortunately, it is not far away. It takes 15 minutes by car. Overall recommendation. We can have further understanding of the natural landscape of Changbai Mountain.
