Four Great Inventions of Lu Ban

Lu Ban's four great inventions are as follows: saw, ruler, planer and stone mill.

1, the origin of Lu Ban's invention of saw:

Once Luban was accidentally scratched by a leaf when he went up the mountain to cut down a tree, so he began to observe the shape of the leaf and saw sharp teeth on both sides of the leaf. Suddenly, a locust flew over and chewed with its mouth open, and it was inspired. If you use this to cut down trees, it must be fast, so you start to invent it.

2. The origin of the ruler invented by Lu Ban:

Musical ruler is also called Yuanfang, because it was invented by Lu Ban, and it is also called Lu Banchi. It has been handed down from the people and is engraved with the word "auspicious". Folks have always used this to specify the length of things, such as doors and beds. This ruler is eight feet long. Now the tape measure is also printed and distributed by it.

3. The origin of Luban's invention of airplane:

This is Lu Ban who saw farmers working in the fields and leveling the land with rakes. So he was inspired. He made a flat-edged knife according to the rake, covered it with an iron piece and pushed it on the wood several times. The surface of wood is flat and smooth.

4. The origin of Lu Ban's invention of the stone mill:

Before there was a stone mill, every household used a stone pestle. One day, Lu Ban saw that an old woman was not strong enough to use a stone pestle, so he helped her turn the stone pestle. When Lu Ban saw that the wheat had been ground, he had a whim and found two big stones to make a disc, slotted it and pressed it on the wooden handle. When grinding again, he found it much easier, so he was used by later generations.
