Write a short article in your own words about how Lu Ban invented the umbrella.

A long time ago, there were no umbrellas in the world. At that time, it was inconvenient for people to go out in summer. The sun burned my skin. Wet your clothes on rainy days. Lu Ban is eager to help people solve this difficulty. He thought, if only he could make something that can shelter from the wind and rain.

Lu Ban used a lot of brains. Later, he and several carpenters built a pavilion by the roadside. The top of the pavilion is very sharp, supported by several pillars around it. Then, they built a pavilion every other road and built many pavilions. In this way, it is much more convenient for people to walk. When it rains, hide; The sun is uncomfortable. Take a rest and catch your breath.

Lu Ban did a good thing for everyone, and everyone was very grateful to him. But Luban himself was not satisfied. He thought, what should we do if it doesn't stop raining? People can't always stay in the pavilion.

We must find another way! Lu Ban thought: If only we could make the pavilion smaller and let everyone take it with us! But how can we make the pavilion light and smart? For this matter, he can't eat well and sleep well.

Luban thought for many days, but he still didn't come up with it. One day, it was extremely hot, and he was sweating while working. Suddenly I saw many children playing by the lotus pond. After a while, a child picked a lotus leaf and put it on his head.

Lu Ban thought it was fun and asked them, "What are you doing with a lotus leaf on your head?" The child said noisily, "Master Lu, look, the sun is like a big fire wheel. We are not afraid of the sun with lotus leaves on our heads. "

Lu Ban grabbed a lotus leaf and looked at it again and again. Lotus leaf is round, with veins on one side and a cover on the head, which is light and cool.

Lu Ban's heart lit up. He hurried home, found a bamboo, chopped it into many thin strips, and made a shelf according to the lotus leaf; I found another sheepskin, cut it into a circle and put it on a bamboo shelf. "All right, all right!" He cried happily, "This thing can shelter from the wind and rain and shade the sun, and it is also very smart."

Lu Ban's wife heard him shout and ran out of the house and asked him, "What happened?"

Lu Ban handed the newly made thing to his wife and said, "Try this thing. Everyone takes it with them when they go out. They are not afraid of rain or sun."

Luban's wife looked at it, thought about it, and said, "It's not bad, but the rain stopped and the sun went down, so it's not convenient to walk with such things." If only it could be put away. "

"Yes, yes!" Lu Ban was very happy to hear this, so he started with his wife, changed this thing into a movable one, spread it out when it was used, and put it away when it was not used. What is this thing? This is our umbrella today.
