Although it's half-way up the hill, the air is very cold. Fortunately, it's still warm in the tent, and we live in the cave, so we don't feel very cold.

After a short rest, I felt that the air around me seemed to be getting colder and colder, and there was a whirring wind outside, as if it was blowing.

The climate here is really weird. It was fine just now. After a while, it began to blow hard.

Now that Wu Mingmei is asleep, I leave my tent and go outside the cave. I can see the heavy snow flying outside. The snow on the ground is already thick....
