On December 4, I went to Jiuzhaigou for a tour. This season, compared with other seasons, there are fewer tourists to Jiuzhaigou. The scenic spot is very quiet. Jiuzhaigou in this season has the characteristics of this season. There is no way to go to the viewing platform in winter, but it is very quiet to look at the long sea on the trestle road. Listening to the guide's lobbying about the 550,000-year-old history of Changhai, I was shocked at once! _________
