Who invented the umbrella? There are many different opinions. Some people say that the people of ancient Egypt invented it, some say the Romans invented it and some say Lu Ban invented it in ancient China. There's an interesting story about its invention in China.
A long time ago, a young man and his wife decided to go to a scenic spot called the West Lake for a picnic. But then it began to rain heavily. The pair, along with other travellers, hurried to find shelter at nearby pavilions (亭子).
From there, they found out that they could look out at the beautiful scenery, but they were sad that they could not go for a walk.
"I wish I had a movable pavilion," the wife said. "A movable pavilion?" the young man's eyes widened. "Of course!"
