yang jin » yang jie, yang jun, shang jin
ying jin » jing ji, yang jie
yan min » han min, kan min, yang mind

• The words AND, OR and NOT may confuse the search; try adding quotes: "doing hoang yu hua best ((yan min) or (((yang jin) OR (ying jin)))) dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: doing hoang yu hua best ((yan min) or (((yang jin) OR (ying jin)))) dang hai ;*.
