Perhaps you should try some spelling variations:
yuan ting » huang ting, yuan kang, yuan lin
yuan ming » kian ming, tuan minh, chan ming
yuan tan » huan t'an, yuan kang, yuan wang
hua rain » hua ban, hua ren
yang jin » yang jie, yang jun, ying jin
wong sau » wong sam, wong siu, wong shiu
yan jiu » yang jie, pang jiu

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 ((yuan tan) OR (((yuan ting) OR (yuan ming)))) hua rain ((yan jiu) OR (yang jin)) wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yuan tan) or (((yuan ting) OR (yuan ming)))) hua rain ((yan jiu) or (yang jin)) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yuan tan) or (((yuan ting) OR (yuan ming)))) hua rain ((yan jiu) or (yang jin)) wong sau ;*.
