One day while Lu Ban and his younger sister were visiting the West Lake in Hangzhou，they were caught in a sudden heavy rain and had to turn back．"What a pity，" thought sister Lu．

When they got home，she told her brother，"You are the best craftsman around here，trot I will make a bet with you．Let's see who can invent something that will let people enjoy the scenery even in the rain．"

Lu Ban laughed．"All right．" he said，"But there must be a time limit．Three days?"

"No，just one night．We start tonight and stop at the first cook's crow．"

Lu Ban was surprised，"All right，it's a bet．"

When it turned dark，Lu Ban started building a pavilion （亭子） at the lakeside．Under the pavilion，people would be able to enjoy the scenery，even in wet weather．When he finished，he went home and looked through the window of his sister's workshop．All was quiet inside．

Lu Ban went back and built another pavilion，then another，and still another．He built nine and started working on the tenth，but before he could finish，he heard a cock crowing，so he stopped．

Soon the sun rose．As he stood by one of the pavilions wondering what his sister had done，Lu Ban saw something coming towards him，something like the roof of a pavilion．Under it was his sister．

As she came nearer。Lu Ban saw that she was holding a bamboo pole（竹竿） which had something round and flat（平的）at one end and covered with silk of many colors．

“What a useful thing! How clever!” he cried out，examining his sister’s invention．

Sister Lu smiled．“Mine can only be used by a single person, while yours can he used by many at the same time．What’s more，it was your design that gave me the idea．The scenery looks so much nicer with your pavilions．”

Some people say that was the beginning of the Hangzhou umbrella．

1．He was visiting the West Lake when it began to rain．

2．The word “craftsman” means“发明家”in Chinese．

3．Lu Ban built nine pavilions．

4．Lu Ban invented the same thing as his sister．
