A Lost Bag
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.

However, he decided to find the girl and thank her.
