chang tao » chang ha, chang mae, huang tao
yang jin » yang jie, yang jun, ying jin
wong yue » wang yue

hua ren » hua chen
han min » han men, kan min, chan ming

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: yuan chang tao hua ren ((yang jin) OR (han min)) ((wong yue) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan chang tao hua ren ((yang jin) or (han min)) ((wong yue) OR (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: yuan chang tao hua ren ((yang jin) or (han min)) ((wong yue) OR (hong yu)) ;*.
