Wang Yan, 22, used to be a nurse in a private clinic in Jinan, east China’s Shandong province. Unfortunately her brother got leukemia and the treatment would cost a large sum of money. To make more money, she decided to sell sweet potatoes in the street. She gets up at 5 a.m. every day to roast sweet potatoes and goes out to peddle them in the street at 8 a.m. She can earn 180-200 yuan a day. (Photo/ iqilu.com)
