Very lucky to see the beautiful view of Tianchi, very spectacular. Since it is the off-season, the number of tourists is very small and it feels good. And there are only 4 tourists on the scheduled day trip to the North Slope. We are fortunate to use the Buick business car. The tour guide and driver are very shy. The delay of the round-trip plane is very crazy, and I hope Trip.com will give more assistance. Because of the heavy rain in Changbai Mountain, I stayed in Changchun for one night and refunded the first night's room rate. This is very good.
