Primary school students' self-protection cases

During the National Day, several college students went camping. Several college students got lost because of their lust for the scenery in the mountains. Surrounded by mountains and jungles, it began to rain again, the direction was difficult to distinguish, and it was wet and cold. We had to find a cave to shelter from the rain.

The next day, everyone still couldn't find a way out. Kobayashi remembered some ways to survive in the wild and asked for help, so he took two people to make a fire with pine branches at the top of the mountain. After the fire, he covered it with grass, and suddenly, white smoke rose upward. They were finally discovered and out of danger.
