Perhaps you should try some spelling variations:
yang hua » wang hua, yang hui, ying hua
yang jie » yang jin, yang di, yang jui
wong sau » wong sam, wong siu, wong shiu
yang yi » yang di, yang xi, yang jui
yan jiu » yang jin, pang jiu
yan ji » ban ji, pan ji, san ji
wang » wing, wan, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang hyoung ((yang hua) or (yang yi)) gene ((((yan ji) OR (yan jiu))) or (yang jie)) wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang hyoung ((yang hua) OR (yang yi)) gene ((((yan ji) OR (yan jiu))) OR (yang jie)) wong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang hyoung ((yang hua) or (yang yi)) gene ((((yan ji) OR (yan jiu))) or (yang jie)) wong sau ;*".
