yan jiu » yang jie, pang jiu
hua ren » hua chen
kan min » kian ming, kyaw min, tang min

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: wang ((yan jiu) OR (yang jin)) hua ren ((kan min) OR (han min)) ((hong hong) OR (hong pong)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((yan jiu) or (yang jin)) hua ren ((kan min) or (han min)) ((hong hong) or (hong pong)) ;*.
