chang tao » chang ha, chang mae, huang tao
ying jin » yang jin, jing ji, yang jie
wong yue » wang yue
tao hua » tan hua, tuan hua
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 ((ying 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 ((ying jin) or (han min)) ((wong yue) OR (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: yuan chang tao hua ren ((ying jin) or (han min)) ((wong yue) OR (hong yu)) ;*.
