Mr Wang is a famous doctor. One day he received an invitation to a medical conference. He was happy and accepted it. He got ready for the speech and put the notes into his bag. Then he went there by train. Unfortunately, his bag fell down from the window of the train while the train was running. Mr Wang was very worried, but he knew the train couldn't stop for him to pick the bag up.
When the bag fell to the ground, a girl just went past the railway. She saw the bag and picked it up quickly. Inside it, she found the notes and the address of Mr Wang. She thought the owner must be worried about it, so she hurried to the post office at once to send it to Mr Wang.
Some days after, Mr Wang received his bag before his speech was made. He was both happy and surprised. In fact, thanks to the girl, his speech could be successful. He didn't know who the sender was. However, he decided to find the girl and thank her.
王大夫是一位名医。一天他接到一份参加医学大会的邀请函，他十分高兴并决定去参加这次大会。他准备在会上发言，并把讲稿装到包儿里。随后他乘车前往。但不幸的事发生了，他的包在旅途中掉到了车窗外面。王先生十分焦急，但火车不可能停下来，让他去捡包。
当王先生的包掉下来的时候，一个姑娘正好路过铁道线。她看见那个包并把它捡起来，打开一看，只见里面有一些稿子还有王先生的地址。她想失主一定很着急，所以就立刻跑到邮局把它邮给王先生。
几天以后，王先生在发言之前收到了他的包。他真是又惊又喜。他演讲能获成功还得归功于那个小女孩呢！他并不知道女孩的姓名，但他决心一定要找到她向她致谢。
