The story about Lu Ban's invention

The invention was finally attributed to Luban's wife. In ancient times, rainy days and hot summers plagued people, and people had to hide under small pavilions and could not go out. There is a legend that Luban built many pavilions around his neighbors for everyone to use, but he still couldn't let people in and out freely in the stormy season. Lu Ban's wife made a lightweight bamboo pavilion out of oiled paper-an umbrella, of course, according to the style of her husband's pavilion. His wife said to Lu Ban, "The house you built can't be moved. My umbrella can be taken with me and can provide protection all year round. "
