What methods can primitive society use to make a fire and save the fire?

According to the current archaeological data, cavemen about 18000 years ago have left the stage of preserving natural kindling and mastered the technology of artificial kindling. The earliest manual ignition method was friction ignition. Our ancestors often saw that striking stones sometimes produced sparks. When drilling, sawing and scraping wood, the wood would heat up and even produce fireworks. These phenomena have been repeated countless times, and people are gradually inspired to understand the causal relationship between friction and fire, thus inventing the technology of friction fire. "Everything is Wrong" in ancient times about people "drilling for fire (drilling for fire, flint for flint; The description of "burning wood when rubbing or colliding with flint" and "burning wood when rubbing wood" in Zhuangzi Foreign Objects reflect the situation of early artificial combustion. Mastering the artificial fire technology means that human beings have controlled this powerful natural force that changes matter for the first time. Mastering artificial lighting technology is a great invention in the history of human science and technology, which has opened a new era in human history. Engels praised the use of fire in "Anti-Turin" for "making people dominate a natural force for the first time, thus finally separating people from the animal kingdom.

Engels praised the use of fire in "Anti-Turin" for "making people dominate a natural force for the first time, thus finally separating people from the animal kingdom." Fire is the basis of diet and cooking. It should be said that with fire, there is a food culture. Before the birth of fire, the ancestors could only live a primitive and animal-like life. The so-called "eating the food of vegetation, the meat of birds and beasts, drinking their blood, like their hair." As Han Feizi said, "People eat fruits and clams, and their stomachs are injured by foul smell, which leads to many diseases." After the birth of fire, "guns are familiar to people, making people have no abdominal diseases and different from animals." The inventor of fire, China, has always been said to be a man who drilled a fire to make a fire. Archaeologists preliminarily speculated from the stone tools used by Beijingers in Zhoukoudian that China people began to use fire consciously, about 500,000 years ago. Corpse: "Look up at the stars, look down at five trees and think it's fire." According to the five elements of yin and yang, fire is born in wood, so people use wood to make a fire. "The History of Taoism" says that embarrassing people is to watch the dry elephant, watch the heart and get out of the fire, and make embarrassment. According to the ancients, "Chen Xin" is called "Xinsu", that is, "Big Mars". The so-called "five wood" refers to five kinds of wood that are considered suitable for fire at the right time. That is, "Yu; Liu Qing, so bring it in spring; Jujube: apricot red, so eat it in summer; Sang: Huang Zhe, so I took it at the end of summer; Tussah: (Mukui) white, so take autumn; Sophora japonica; Suntanned, so bring it in winter. " After a man drills a fire, his wooden drilling tool is called fire. Later generations invented using metal to take fire from the sun, so there are two kinds of "wood fire" and "yang fire". "Huainanzi" notes: "Yang Sui sees the sun and burns into a fire. Yang Xiang, Jin Ye. The sun is three or four feet high, and if you cling to the sun, you will be angry for a moment. " "Notes on Ancient and Modern Times": "The pith of yang is copper, which is shaped like a mirror. When you look at things, the scenery falls and you light a fire at the sun. " Before the Han Dynasty, it was called "open fire" to make a fire with incense, and "national fire" to make a fire with wood. According to the "Great Wish" and "Great Reconnaissance" in Zhou Li, the yang marrow is taken from the sun and close to the sky, so it is used for divination and sacrifice. Wood is taken from five trees and is close to people, so it is used for cooking. After the Han Dynasty, when metal struck a stone, it could also be rubbed to make a fire. Therefore, a simple piece of iron can also be turned into an yang sui. When people go out, they usually wear Yang Xiang and Mu Xiang on the left side of their waist to make a fire at any time. In addition, there are tinder made of wormwood and salt water. When the spark falls on the tinder and burns due to friction, the fire is ignited by "lighting a candle". The so-called "hair candle" is a small piece made of peeled hemp stalks, which is five or six inches long. At first, it flows with sulfur and burns when it meets fire. Where there is fire, there is a stove. The person who made the stove said that it was Emperor Yan, and Huai Nanzi: "Emperor Yan died with fire as the stove." Note: "Yan Di Shennong ruled the world with fire and died in the kitchen god." One is the Yellow Emperor: "Continued Beginning": "The Yellow Emperor sets the stove." Therefore, "Everything must be the original" said: "The Yellow Emperor cooked and died as a kitchen god." And Vulcan, generally speaking, is Zhu Rong. Huainanzi? 6? 1 "Note:" Ng Wui and Zhu Rong are the fire of Gao Xin, and the god of death is Vulcan, leaning against the stove. "Historical records? 6? 1 Chu family: "Li Dong lived in the fire for Di Ku Gaoxin and made great contributions. He was able to integrate into this world, and Di Ku was named "Zhu Rong". "The Book of Rites Moon Order": "The moon exists, and its emperor, its god Zhu Rong, and its sacrificial furnace are sacrificed to the teacher. "The original shape of the stove was to dig holes in the ground. Today, the furnace excavated from Xi 'an Banpo site is a kind of double furnace, that is, two fire pits are dug on the surface. These two pits are separated on the ground, but they are connected underground. A pit is where firewood enters, a pit is where people leave, and the hole connected with the two pits is the stove door. Banpo in Xi 'an has a history of six or seven thousand years, and its inventor should be Emperor Yan rather than Yellow Emperor. It is estimated that the Yellow Emperor was in power about 4600 years ago. Emperor Yan passed down seventy generations before the Yellow Emperor, about six or seven thousand years ago. By the Warring States period, the production of stoves had been perfect. " "Zeng Lianzi" notes: "One furnace has five protrusions (protrusions: chimneys), and there are many people who distribute cigarettes, and it is cooked for ten times. "
