About 10 years ago, when I was a college student, I was working in the shop at my university’s Museum of Natural History. One day, I saw an elderly couple come in with a little girl in a wheelchair (轮椅).

As I looked at this girl, I saw that she was seated on her chair. I realized she had no arms or legs, just a head, neck and body. She was wearing a little white dress with red dots (圆点). As the couple wheeled her up to me, I was looking down at the cash register (收银处), I turned my head toward the girl and gave her a wink (眨眼). As I took the money from her grandparents, the girl gave me the biggest smile I have ever seen. All of a sudden, her disability (残疾) disappeared. All I saw was this beautiful girl, whose smile gave me a new sense of life. She took me from being a poor, unhappy college student and brought me into her world of smiles, love and warmth.

That was 10 years ago. I’m a successful businessman(商人) now. Whenever I am down and thinking about the troubles of the world, think about that little girl and the life lesson she taught me.
