Sun Ya

Sun Yat-sen showed extraordinary ambition as a child: learning the house of a fellow villager was forcibly occupied, he dared to loudly challenge the bullying officers; seeing his elder sister was going to bind her feet which was painful, he righteously questioned this practice.When he was only 14, he decided to follow his elder brother to San Francisco to learn new things.Why could the teenage Sun Yat-sen make such a bold decision?Why did he changed the course and transformed from a young medical student into a revolutionary?
