We went there in February. There was snow at the foot of the mountain. We could see how thick the snow was on the mountain. Choose the Chengbanyue route, 9.6 km one way, we arrive at the starting point of the route at about 8:30. According to the internet, there are many ice claws, climbing rods, climbing shoes and gloves. We also wear knee pads in advance, and after finishing equipment and taking photos, we begin to climb at about 8:50. I have to say that Koreans are walking at a very fast pace. I feel that I can't walk with these equipments. I can only walk at my own speed. Fortunately, they will take a break after a short walk, and we have been walking unnoticed at the beginning, so the time to arrive at the first rest point is similar. The first section is 4.1 km. It took more than an hour because of its gentleness. The next 3.2 km immediately showed the colours, all slopes. It took about an hour and a half to reach the second rest point at 11:30. This is the place where you are required to arrive before 12 o'clock. After a short rest, the more terrible thing is the third paragraph. Although only 2.3 km is left, I feel that I have been walking for a long time, but I only walked several hundred meters. At the end of the 500 meters, I went crazy. Without the barrier of trees, the wind suddenly became so big that I could blow people down and even stop and wait on the side railings. Behind it is even more absolute, even the railings are gone, beside it is the cliff, but the wind direction is crosswind, even if it falls down, it is also inside. People who have returned to the opposite side or who have the same climbing behind have the courage to go down. Because of poor visibility, people will disappear in a twinkling of an eye, accompanied by only the manic wind and the unknown road ahead, such embarrassment and inner struggle can only be seen in person. Only in the field can we experience this unforgettable experience for a lifetime. Such weather conditions can not see anything when we reach the top of the mountain. We should return with a little bit left. It's still important to have our own lives. The return journey is no longer repeated, and the wind will be much less if it goes down a little. After replenishing food at the second rest station, it continues down the mountain and finally returns to its starting point at 4:30. Although I didn't see any special scenery, the experience is enough to recall
