The first time I went to Changbai Mountain was in the autumn ten years ago. I was lucky to see the perfect Tianchi Lake. The autumn scenery was beautiful. The underground forest was full of natural oxygen bar, and the negative ion shelter exploded. It was very comfortable to walk in. This is the second trip to Changbai Mountain. At this time of the Spring Festival, it's a totally different scene. It's beautiful. Five-star recommendation. Snowmobiles are really exciting. Ten-year tickets don't go up very well. Some people think that off-road vehicle 80 is too expensive to go to Tianchi. After experiencing it, you will feel that 160 should be given.
