I once met a particularly embarrassing thing, but it was quite interesting to say. I went to climb Huangshan Mountain in November, originally thinking of sleeping in a tent. Carrying the rented tent, I climbed all the way to Guangmingding. During the day, the temperature was quite high, and enjoying the scenery along the way was very pleasant. When it was getting dark, it was super cold. As a result, Guangmingding didn't allow me to set up a tent, saying it was ok below. As a result, I went down to the tent in front of the hotel, and the tent was set up. As a result, I found that there was no air cushion. This is to let me know who is on the cold stone directly. It was completely dark in the sky, and there was a quilt for rent outside. I was super happy when I heard it, thinking about renting it, but when I thought about it, I came to experience the feeling of living in a tent in the wild, so I didn't rent it. I froze all night, curled up in a small sleeping bag, and the wind was biting. Fortunately, I didn't get sick the next day, didn't watch the sunrise, and froze all night. My heart is broken. But all the way down the mountain, I saw the sea of clouds when I first came to Huangshan, and it was still worth it.
