In ancient times, there was no lighter. How did they light the fire?

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.
