In the wild, camp accommodation was a kind of military or sports training project, which became the leisure activities of the general public. Campfires are usually needed to be made. They can not only prevent the invasion of wild animals, but also can be used to burn, bake, cook or heat camping food. Therefore, it is very important for camping to make fire.
Camping is a kind of leisure activity. Usually campers take tents, leave the city and camp in the wild for one or more nights. Camping is usually associated with other activities, such as hiking, fishing or swimming. Camping, as a kind of avant-garde outdoor tourism, has been tried by more and more people. With the growing boredom of urban life and the rapid popularity of Internet, more and more people gather in the name of "donkey friends" to live outdoors in leisure time.
