According to legend, ten thousand years ago, there was a country that knew nothing about four o'clock in the day and night. If people don't die, they will ascend to heaven if they are tired of the world. State-owned wood, also known as fire tree, bends around and clouds come out. If there is a bird, peck at the wood with its beak and make a fire. Inspired by this, a saint broke a branch and drilled wood to make a fire. People call this saint a saint.

Sui Renshi is a legendary inventor, which has been recorded in ancient books before Qin Dynasty. According to "Five Mistakes of Everything is done", "In ancient times, there were fewer people and more beasts, and the people were invincible; ..... People eat fruits, clams, clams, and the foul smell hurts the stomach and causes many diseases. There are saints who drill fire to make it stink, and the people call it (味味) to be the king of the world, which makes people embarrassed every day. " "quotations from corpses" said: "one looks up at the stars and overlooks five trees as fire." "Notes" said: "It can be seen that state-owned trees are famous all over the world. Later, saints swam to their country, birds pecked at trees, and they lit a big fire. The sage felt awkward because he used twigs to drill fire. " "Ancient History Examination" said: "At the beginning of ancient times, people sucked dew, ate grass and fruits, lived in mountains, ate birds and animals, ate clothes and feathers, and ate fish, turtles and clams near water without cremation, which was harmful to the stomach. In order to make (yes) saints come out, fire is king, drill to make a fire, teach people to cook, and cast gold as a blade to make people happy. " "Three Graves" says: "Sui people teach us to eat with guns, drill wood for fire, have a platform for preaching, and have a strategy for tying ropes." "Hanshu" also has a record of "teaching people to cook, nourishing people's interest, avoiding odor and removing poison". Mr. Shang He Bing, a famous scholar in the late Qing Dynasty, said: "Fire comes from scratch and its invention is difficult." The emperor felt that the forest burned himself, and he knew that wood hides fire. I don't know. After many attacks and tests, it's tricky to drill wood. His merits and deeds have entered the nest again, and he is the emperor. It can be seen that the shackles at that time were sacred and the interests were profound. "He also said," In other words, it is said that cremation and diet started in Xixi, so it is considered as a number. Do you know that since man invented fire, his wisdom has not known how to eat? "The gunner wrapped the meat and burned it, burning its hair to make it familiar. In cooked food, Suiren not only invented artificial lighting, but also created cooked food.
