In ancient times, human beings lived like animals, and people used to eat raw food. Fire has existed in nature for a long time, but it exists in the form of volcanic eruption, lightning and spontaneous combustion. Primitive people were very afraid of fire. Although the food cooked in the fire is delicious and easy to digest without getting sick, I still dare not and don't know how to put out the fire.

In Shangqiu today, there is a tree called wood, also called fire tree, which twists and turns and clouds come out from it. If there is a bird, peck at the wood with its beak and make a fire.

One person was inspired by it, so he broke off the flint branch and got into the other person's body to take out the fire. Since then, people can eat cooked food at any time, and the variety of food has also increased. People elected this saint as king, and called him Sui Ren. Where there is fire, there is light, so this country is called Tunming Country.

Sui trainers invented drilling wood for fire and taught people to cook food, which ended the history of ancient humans eating like animals, distinguished the living habits of humans and animals, created Chinese civilization, and was regarded as the "ancestor of fire" by later generations. Later generations listed Suiren as the head of Huang San, honoring him as "Emperor" and "Huang Sui".

Fire, first seen in Oracle Bone Inscriptions, is pictographic. The shape of fire in Oracle Bone Inscriptions is like the burning time and the shape of flame. The word "golden slow fire" was changed to the pictograph of the anchor shape representing the flame, and then changed to the pictograph of the flame with two points.

Two of them indicate that something in the flame is coming out of the nearby generator, and the whole word depicts the hieroglyphics of the fire glowing and heating around. Later, it evolved into the shape of "fire", divided into four strokes, but still retained a little light and flame.
