Frog lover turns passion into a promising business

Former opera singer sets up lucrative pet breeding base containing dozens of species

While millions of Chinese have recently become obsessed with a mobile game about a traveling frog, a man in Chongqing has been raising amphibians as pets for years - and has turned his hobby into a promising business.

Li Shu, 31, used to be a Sichuan Opera singer and owned a dance club. But he loved collecting weird things, and in 2006, he bought an ornate horned frog at a pet market.
