Li Tie, left, and Zheng Chu, co-founders of the app Runtu, talk about their business beside a pool near their offices in Guangzhou, capital city of South China's Guangdong province. Runtu aims at connecting migrant workers who come from the same hometown but work in Guangdong. Li used to be a media celebrity and told his followers on twitter-like Sina Weibo that he quit his job to "start a business to earn money and live a happy life." [Photo/qq.com]
