What are the legends and stories of Luban?

Lu Ban is a carpenter who works with wood all day. He is very skilled, especially good at cutting wood into the required shape with an axe. The sentence "Teach people to play with an axe" means that anyone who wants to play with an axe in front of Lu Ban is overreaching.

This shows Lu Ban's proficiency in using an axe. However, it is impossible for Lu Ban to cut the wood smoothly with an axe, especially when it comes to wood with thick grain and many scars. In order to solve this problem, Lu Ban pondered during the day and thought at night. First, he made a thin axe, which was quickly sharpened. Much better than before, but still not ideal.

So Luban ground a small and thin axe, covered with a piece of iron, leaving only a narrow blade. Luban won't cut it this time. He pushed the wood with this narrow blade. Push, the wood pushed down a thin layer of sawdust.

After a dozen pushes, the surface of the wood is flat and smooth, which is much better than that cut with an axe in the past. But when this thing is pushed in your hand, it is both stuck and invalid. Lu Ban made another wooden pedestal and put it in. So the plane was born.

2. Graphite

Luban travels all the year round, working for others. On this day, he was busy all morning and sat down to have a rest. A family is going to cook, but there is no flour. They took some wheat, put it in a mortar and pounded it with a heavy pestle.

The wheat masher was so tired that he sweated a little. Because the wheat grain is oval, the force is small and cannot be broken; I was so excited that I smashed the wheat and ran. I'm really anxious. That's how people used it at that time. Luban is determined to reform it and solve difficulties for people. ?

Another day, Lu Ban came to another place to work and happened to see an old lady pounding wheat. The old lady is too old to lift the stone pestle. She took a stone pestle and studied the wheat in the stone mortar. Lu Ban walked over and saw that many wheat grains in the stone mortar had been ground into powder. Lu Ban was inspired by this.

After returning home, Lu Ban asked his wife Yunshi to find two stones. He chiseled the stone into two large disks and carved a groove on one side of each disk. He also installed a wooden handle on one of the disks. The neighbors were surprised. What does Luban do?

Everyone gathered around to watch. I saw that Lu Ban stacked two disks together, and the two sides of the gouge were connected, with a wooden handle on it and a shaft in the middle. He put the wheat grain in the middle of the disc and then turned the stone disc on it. Wheat grains are quickly ground into flour. Everyone is very happy. Luban really made a great contribution to people!

3. Invent the class ruler

Another sign of Lu Ban's invention is that he can correctly draw a right triangle, also called a class ruler, and can tell craftsmen which sizes are irregular and which ones are unlucky according to the rules of divination (geomantic omen). These rulers are still available in Hong Kong today. Lu Ban attached great importance to the invention of the saw.

Or inspiration comes from a blade of grass with a toothed blade that cuts a finger, or seeing a cricket cut and eat food with its sharp teeth and leave. Anyway, most of them are described like this. Luban and craftsmen were asked to cut down a lot of wood. After chopping for several days, they were exhausted and their axes were dull.

At this time, Lu Ban suddenly cut his finger by a blade of grass. He immediately thought: It must be a good way to make a tool for cutting wood. He chose a bamboo and cut a row of teeth on its edge with an axe. This new saw cuts bark easily. When he sawed the tree horizontally back and forth, the soft bamboo teeth were quickly polished. However, this proves the principle that a saw can cut wood.

So Lu Ban put down his hand and went to the blacksmith to prepare an iron plate as hard and sharp as an axe, and then made it into a tooth shape. With this first-hand saw blade, Luban can use it to cut wood accurately and effortlessly on the wooden frame.

Step 4 invent umbrellas

In ancient times, rainy days and hot summers plagued people, and people had to hide under small pavilions and could not go out. There is a legend that Luban built many pavilions around his neighbors for everyone to use, but he still couldn't let people in and out freely in the stormy season.

Lu Ban's wife made a lightweight bamboo pavilion out of oiled paper-an umbrella, of course, according to the style of her husband's pavilion. His wife said to Lu Ban, "The house you built can't be moved. My umbrella can be taken with me and can provide protection all year round. "

5. Invented Mo Dou.

Another very important tool invented by Lu Ban is the Mo Dou used by craftsmen (used to set up construction projects), which may be inspired by his mother. At that time, his mother was cutting and sewing clothes. Looking at all this, Lu Ban saw that she used a small powder bag and a thread to print out the desired cutting shape first.

Lu Ban transferred this practice to Amodou. He pinched both ends with a thread (soaked in Mo Dou) and placed it on the material to be printed with the required lines. At first, Lu Ban and his mother had to grab both ends of the line.

Later, his mother suggested that he make a small hook and tie it at one end of the line, thus freeing her from such chores and making it possible for her to do it alone. In memory of Luban's mother, craftsmen still call it Mo Dou Banmu.
