Tell a traditional story of China in English.

You didn't say much. Let's see if the following is ok.

Waiting for unexpected gains

Thousands of years ago, there was a farmer in China. He does farm work every day, which is very hard. However, he got little.

A few days ago, when he was on the farm, suddenly, a rabbit ran into a nearby tree and died. He got a rabbit for dinner as easy as blowing off dust. So he decided to wait for more and more rabbits to die in accidents. Finally, he died because there were no more rabbits. This story tells us that no pains, no gains. A person can't have wealth forever. If you want something, you should make your efforts.
