Is Robinson Crusoe about Lu Ban or Lu Xun?

No, it's Ruban. It is said that one year, Luban accepted the task of building a huge palace. The palace needed a lot of wood, so Lu Ban sent his disciples up the mountain to cut down trees. Since there was no saw at that time, his disciples had to cut down trees with axes, but the efficiency was very low. The craftsmen work hard every morning. They are exhausted and can't cut down many trees, which is far from meeting the needs of the project and delaying the progress of the project. Seeing that the project deadline is getting closer and closer, I am anxious for Luban. To this end, he decided to personally go up the mountain to see the situation of cutting trees. When going up the mountain, he accidentally caught a handful of weeds growing on the mountain, but suddenly cut his hand. Luban was very surprised. Why is a grass so sharp? So he picked a leaf and observed it carefully. He found many small teeth on both sides of the leaf. These little teeth are very sharp when he touches it gently. He knew that his hand had been cut by these small teeth. Later, Lu Ban saw a big locust gnawing leaves on the grass. The two large molds are very sharp. As soon as they opened and closed, they quickly ate a big piece. This also aroused Luban's curiosity, and he caught one. It is found that there are also many small teeth on the two big dies of locusts, and locusts bite off grass leaves by these small teeth. These two things left a very deep impression on Lu Ban, and also gave him great inspiration. He fell into deep thinking. He thought, wouldn't it be sharp if the tools for cutting wood were serrated? It's much easier to cut down trees. So he made a bamboo chip with many small serrations from a big bamboo, and then went to a small tree to do experiments. The result is really good. After several strokes, the bark was torn, and after several tugs, the small trunk was pulled into a deep ditch. Luban is very happy. However, because bamboo chips are soft and have poor strength, they cannot be used for a long time. After a while, some small serrations were broken and some became dull. Bamboo chips need to be replaced. This will affect the speed of cutting down trees, and it is also a great waste to use too many bamboo chips. It seems that bamboo chips are not suitable for making sawtooth, and a material with higher strength and hardness should be found instead. At this time, Lu Ban thought of iron filings. So they immediately went down the mountain, and the blacksmith helped to make iron pieces with small serrations, and then went up the mountain to continue their practice. Lu Ban and his disciples each pulled one end and pulled it up on a tree. I saw them coming and going, and they soon sawed off the tree, which was quick and labor-saving, so the saw was invented. Before Luban, there must be many people who were cut off by Yemo. Why was it that only Luban was inspired to invent the saw? This is undoubtedly worth thinking about. Most people just think that this is a trivial matter in life and it is not worth making a fuss about. After the wound heals, they tend to forget it. However, Lu Ban has strong curiosity and correct ideas. He paid great attention to observing, thinking and delving into some small things in life, looking for ways and ideas to solve problems, and even obtained some creative inventions. This tells us a truth. Paying attention to many trivial things in life and thinking diligently will increase a lot of wisdom. After inventing the saw, Lu Ban invented many woodworking tools, which are recorded in ancient books.
