The more stories about Lu Ban, the better!

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.

Second, the story of Lu Ban's invention of the airplane

Ruban works with wood all day. His skill is very high, and he is good at using an axe. He can cut the wood into the required shape in a few strokes. However, it is difficult to cut wood with rough texture and many scars into the required shape. 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. This time, Luban won't cut it. 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.

Third, the story of Lu Ban inventing the saw.

Once Luban went to the deep mountain to cut down a tree, slipped and fell, and his hand was cut by the leaves of a wild grass, bleeding. He picked the leaves and touched them gently. There are sharp teeth on both sides of the leaves. He scratched the back of the hand with these small, dense teeth and even scratched a hole. His hand was cut by these little teeth. He also saw a big locust on a piece of wild grass, and many small teeth were arranged on two big dies, which could quickly grind the leaves.

These two things inspired Lu Ban. He thought, if there is such a toothed tool, wouldn't it be able to cut trees quickly! So, after many experiments, he finally invented a sharp saw, which greatly improved the work efficiency. Lu Ban named this newly invented tool "Saw".

Fourth, the story of Lu Ban's invention of umbrellas.

Once Lu Ban went out with his wife, and it rained when he came back. The two men sheltered from the rain in a gazebo on the hillside. Luban's wife said with emotion, "If only more pavilions could be built, so that pedestrians can have a shelter from the wind and rain!" " "Lou looked at the pavilion and suddenly there was a flash of light. He said to his wife, "I have an idea, as long as everyone goes out with a pavilion!" " "His wife didn't understand, and Lu Ban quickly dragged her home and then got into the workplace. A few days later, Lu Ban smiled and walked out of the house, holding an umbrella, which was made of bamboo and oiled paper.

5. The story of Lu Ban inventing the ladder.

Luban lived in an era of hegemony and wars year after year. At that time, every city had high and thick walls. The soldiers guarding the city closed the gate and stood on the wall to guard. As for the attackers, the weapons in their hands are bows and arrows, spears and the like, and it is difficult to capture the city. Often the city is surrounded for many days, and it is difficult to rush. King Lu ordered Lu Ban to make siege equipment.

Thinking about the past and the future, Lu Ban remembered the short ladder he used when building the house. If you step on a short ladder, you can climb to the roof. If you build a long ladder, you can climb the high city wall. If you can shoot arrows on the ladder, won't you be able to beat off the defenders? So, Luban built a "ladder". This kind of "ladder" can be carefully set up to reach the high city wall, where people can stand and shoot arrows. The ladder in modern fire fighting equipment evolved from this kind of ladder.
