Later on,something changed my life. I still remember that it was a rainy day. I put myself in the rain and walked slowly in the street. Suddenly the rain stopped!I raised my head and found "the sky" was in fact a dark blue umbrella. Then I noticed a middleaged man with one leg on crutch standing behind me. He said to me,"Why not run without an umbrella?If you didn't run,you would get drenched." The man told me that he was a promoter. He once dreamed of being a policeman,but an accident ruined his dream. Though his present job was not suitable for his legs,it was a wonderful start to him. He was very happy that he didn't lose heart and still "ran" on the road of life... I was encouraged by the man's words. I went to a big city and became an assurance representative. After two years' running,I did well and my family condition turned better little by little. Later I returned to school and succeeded in my entrance to university. Life is like this.

PROBLEM: Article: Born with easy-broken bone disease, Zhang Yonghong is only half a meter tall and must use a wheelchair. His thin arms and legs can hardly support any weight, and he is unable to take care of himself. However, his hands are able to produce fine paper-cuts, which will free his daughter from the same disease. To support himself, he learned how to make paper-cut art from his mother. He sold his artwork and taught his techniques in Xi'an for eight years before discovering his young daughter _ the disease from him, leading Zhang to move his family to Beijing for his daughter's better treatment five years ago. The daughter's treatment costs about 30,000 yuan a year. The family's savings was used up in two years, and Zhang was forced to start to sell his work in underground passages with his healthy wife, who soon left him because of the hard life. With a little help from government, he was lucky to meet some kindhearted people in Beijing. A Hong Kong businessman gave 60,000 yuan to him last year to treat the girl and start a small shop on Qiangulouyuan, which is known as a famous hutong that attracts lots of tourists over holidays. Zhang Rui, a university graduate, spends most of her time helping Zhang sell the paper-cuts, translating the stories of the paper-cuts into English and selling the works on the roadside of Nanluoguxiang.

Without this, he can't support the family and treat his daughter," says Zhang Rui, who hopes more people will help Zhang.
