Oct. 12, at 7:30 in the morning, starting from Shuangqiaogou, Siniangshan, the road is in good condition. Occasionally, there are small rockfalls on the road, which are not recommended by novices. It's harder than the national road. There is no car on the road. From 9:30 to the top of the mountain, the temperature is very low and the down jacket must be worn. Ice, snow and mist are rising like a fairyland. Walk a section to check if there is dark ice, there is a very thick snow on the roadside, but it doesn't affect. Driving, from the top down about 100 meters or so, the fog dissipated, the sunshine was bright and white snow covered, the sea of clouds suddenly came into view, and it was worth the trip! It's so spectacular and beautiful. It's broader and more beautiful than the cloud sea of Mount Emei.
