Perhaps you should try some spelling variations:
ming hung » dang hung, fung hung, men hung
ming hua » ying hua, wang hua, ming lu
wong sam » wong sau, wong lai, kong sar
wong siu » wong shiu, kong siu, wong sau
wan yan » wang yan, nan yan, wai yan
yan jiu » yang jie, yang jin, pang jiu
yang » lang, wang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan yan ((ming hua) OR (ming hung)) gene ((yan jiu) or (yang di)) ((wong sam) or (wong siu)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan ((ming hua) OR (ming hung)) gene ((yan jiu) OR (yang di)) ((wong sam) OR (wong siu)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((ming hua) OR (ming hung)) gene ((yan jiu) or (yang di)) ((wong sam) or (wong siu)) ;".
• Adding a wildcard symbol may retrieve word variants: wan yan ((ming hua) OR (ming hung)) gene ((yan jiu) or (yang di)) ((wong sam) or (wong siu)) ;*.
