There are various legends about the invention of umbrellas. It is the widely circulated and documented "Master Lu Ban". It is said that Lu Ban works for ordinary people in the countryside, and his daughter-in-law Yun Shi delivers meals back and forth every day. In the rainy season, she is often caught in the rain. Luban designed and built some pavilions along the way. When it rains, he can hide in the pavilion for a while. Although the pavilion is good, it is always inconvenient to set up more pavilions. Moreover, children's faces change three times a day in spring, and thunderstorms come quickly in summer, even as fast as lightning. Cloud suddenly thought, "if only there were a small pavilion around." After listening to his daughter-in-law, Lu Ban suddenly realized. The powerful and all-powerful inventor of China cut out a piece of cloth, put on a movable skeleton and put on a handle according to the pavilion. Yu is the first "umbrella" in the world, so he came out. According to Jade Chip, the umbrella was invented by Lu Ban's daughter-in-law to take care of her husband who works outside all day. It seems that if you want to apply for a patent, it is more reasonable for the Luban couple to enjoy it. The invention of this umbrella is the product of their love and common concern. In a fashionable phrase, it is the crystallization of love.
