佢連原本個姓Au Yeung都改埋做o yang
Yang was born in Hong Kong during British rule. His parents were both from Shanghai and later moved to Hong Kong. In 2000, when Yang was 13, his family emigrated to the United States and settled in Los Angeles, California. His aunt and grandmother were already living in the US; his parents joined them primarily to allow Yang and his brother, Roy, access to better schools. Yang enrolled at John Burroughs Middle School for eighth grade, then later attended Beverly Hills High School.
