Perhaps you should try some spelling variations:
wang hong » wang yong, wang hyoung, wang lihong
yang hua » wang hua, ying hua, yang jui
yang hui » yang jui, wang hui, yang muxi
gene yan » gene bank, ren yan, see yan
wong sam » wong sau, wong lai, kong sar
won sau » wong sau, wong siu
yan ji » yan jiu, ban ji, pan ji

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

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