Stand by me and be my friend

Colin Pemp, 27, has been working hard to support his ex-Chinese girlfriend for two years, after an accident paralyzed her.

"The hard times have passed, she's getting better day by day. My dream is to see her walking again. I know that will happen soon," says Pemp, from Idaho, United States, who studies Chinese at Suzhou University.

Chen Yahuan, 32, comes from Guangxi Zhuang autonomous region. Two years ago, she was a salesperson at a clothing store in Suzhou, Jiangsu province.
