When Ou Yangyun travelled to the Chinese city of Zhengzhou in February to demand recompense after his bank account containing tens of thousands of dollars was frozen, his family expected him to be home two days later to celebrate the Lunar New Year with his five-year-old twins. Ou, 39, and more than a dozen other victims of one of China's biggest banking scandals had gathered outside a train station in Henan's provincial capital. "Henan banks, return our savings!" they shouted, footage of the protest obtained by Reuters shows.
