Last Saturday Wang Ping went to the fields to catch frogs.Soon he caught a full bag of them. He felt very pleased because he thought he would make a lot of money after he sold them.

¡¡¡¡A few days later, he went to the fields again. But he was surprised this time. When he went up, a crowd of insects attacked him. While crying, he threw his net and bag away, and ran away as fast as possible.
