The use of fire, in the ancient literature of China, there are many records about Suiren's drilling fire, which is a vivid portrayal of this historical stage. For example, as described in "Han Li Wen Jia", "Sui people can only drill wood for fire, and they are familiar with guns, and they have no abdominal diseases, which are different from animals"; "Everything is done wrong" even records that "in ancient times, people ate fruit clams, which smelled fishy, hurt the stomach and made people sick. There were saints who made a fuss and made a big fuss, which made the people happy and made them king of the world, named "Sui people"; In Biography of White Tiger No, it is called "embarrassing people" to drill wood for fire, teach people to cook, cultivate people's interest, and avoid odor and poison. Suiren is equivalent to the era when primitive society in China progressed from using natural fire to making artificial fire. Combined with domestic archaeological discoveries, Yuanmou people, Lantian people, Beijingers and cavemen were all found in the ashes of fire. According to these documents, it is no accident that the Chinese nation is one of the earliest nations to use fire to improve their health, and its civilization and culture are at the forefront of mankind. Because the use of fire, especially the method and use of artificial fire, is of epoch-making significance in the health care history of the Chinese nation. It is the first time that our Chinese nation has mastered natural phenomena and used it to serve its own survival and health care. The Chinese nation invented the use of fire, which can keep out the cold and prevent frostbite and diseases caused by cold; Can prevent animals from reducing the harm to wild animals; Can illuminate, reduce dark birth and eye diseases; In particular, changing raw food into cooked food, on the one hand, reduces gastrointestinal diseases, on the other hand, expands the scope of food and improves food hygiene; "The most important thing is the effect of meat food on the brain marrow, so the brain marrow develops more perfectly." This shows how important the use of fire is to promote the germination of national health care in China.
