Lu Ban's inventions are well known in our country, but there are some things that are not invented by Lu Ban but are mistaken as his inventions, so what are they? Lu Ban's invention - planerWhat did Lu Ban invent? Let's start with Lu Ban's invention - the planer. Lu Ban was a carpenter and was highly skilled in using an axe to cut wood, but it was still difficult to cut wood flat and smooth with an axe. For this reason, Lu Ban made another thin axe, sharpened it very quickly, and chopped it much better than before, but it was still not ideal. Once, Lu Ban see farmers with a rake to rake the ground very flat, he was inspired by it, home will make a flat blade plane knife, covered with a piece of iron, this time Lu Ban did not cut, he used this knife in the wood to push. A push, the wood pushed down a thin layer of wood chips, pushed a dozen, the surface of the wood and flat and smooth, than in the past with an axe can be much stronger, but this thing in the hands of the push when both the hand and not make the force, Lu Ban made a wooden seat, the narrow knife mounted on the inside. The planer was born. Luban's invention - ink bucket Luban invented what? The inkwell must also be mentioned here. Lu Ban created the carpenter's ink pot for marking, which was inspired by his mother's use of a powder bag for marking when she was cutting clothes. When the bucket was first made, Lu Ban had to ask his mother to help him by pinching one end of the line every time he flicked the line. Sometimes, when his mother was making clothes or cooking, she had to put it down and rush to help. One day, Lu Ban's mother said to him, "If you make a small spoon, won't you be able to pinch the inked thread instead of me?" When Lu Ban heard this, yes! He quickly made one. From then on, a person could play the ink line. Until now, carpenters still call this little hook "Banmu". What did Lu Ban invent? Besides the planer, there is another important tool in Lu Ban's invention, which is the stone mill. It is said that people started to use stones to crush or grind grains 6000 years ago, and more than 4000 years ago, people invented a tool called "mortar and pestle" to grind rice. However, the mortar and pestle was time-consuming and labor-intensive, and it could only grind a small amount of grain at a time, and it caused back pains over a long period of time. One day, Lu Ban came to another place to work and happened to see an old woman pounding wheat. The old woman was too old to lift the mortar and pestle. She was holding the mortar and pestle, and she was grinding wheat grains in the stone mortar. Lu Ban went over and saw that many of the wheat grains in the mortar had already been ground into powder. Lu Ban was inspired by this. Back home, he found two large stones, the stone chiseled into two large discs, and in each disc on one side of a groove, one of the large stone discs, the top of the hole and wooden handle, the two stone discs stacked on top of each other, chiseled grooves of the two sides together, the center of the installation of a shaft. He put wheat on the hole in the center of the discs and made it rotate by human or animal power, and was able to grind the grain and wheat into powder, which is the stone mill that used to be widely used in the countryside of our country in the past two thousand years. Lu Ban's Sister's Invention--UmbrellaWhat is there that is not invented by Lu Ban but is mistaken as his invention? Once, Lu Ban and his sister were visiting the beautiful scenery of Suzhou and Hangzhou when it started to rain heavily, so they made a bet to see who would invent the best tool in a month's time so that people could play even in rainy days. The next day, Lu Ban built a pavilion on the road. Lu Ban's sister thought hard, but had no good ideas. Seeing that her brother Lu Ban's pavilion was almost finished, she was even more anxious. One day, when it was pouring rain, a child ran past Lu Ban's sister with a lotus leaf on his head. However, the concave upward lotus leaf accumulated a lot of rainwater, and gradually could not hold up. The child had an idea and turned the leaf over and put it on his head. An umbrella-shaped hat with the convex side up appeared. Lu Ban's sister realized that the umbrella shape had the effect of blocking the rain, and the umbrella was born. A month's time passed, Lu Ban built dozens of pavilions along the Su Causeway, and when he was complacent and thought he was winning, his sister appeared, holding the present umbrella.
