The original plan was to cross to Zhagana from Zagulu Town along Dieshan and Guanggai Mountain Canyon, which is the legendary "Road of Rock". Last night, I prepared all the dry food for three days. In the morning, a heavy snow closed the road. The hotel helped me to the Forestry Bureau to inquire. All three of their checkpoints set up cards to seal the road. Finally, I had to take the national road from Sichuan to Zhagana. From the canyon, it suddenly came in, the mountaintop fairy spirit was floating, and the cliff was a Tibetan village, like a fairyland on earth.
