Perhaps you should try some spelling variations:
wang lihong » wang liang, wang shiyong
wang hong » wang yong, wang hyoung, wang heyong
yang hua » wang hua, yang hui, ying hua
gene yan » gene bank, see yan
wong sam » wong sau, wong lai, kong sar
yang xi » yang di, yang yi, yang jui
ji wong » ji won, ji zhong, kie wong

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) or (wang lihong)) ((yang hua) or (yang xi)) ((gene yan) OR (ren yan)) ji wong sam ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang hong) OR (wang lihong)) ((yang hua) OR (yang xi)) ((gene yan) OR (ren yan)) ji wong sam ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang hong) or (wang lihong)) ((yang hua) or (yang xi)) ((gene yan) OR (ren yan)) ji wong sam ;".
• Adding a wildcard symbol may retrieve word variants: ((wang hong) or (wang lihong)) ((yang hua) or (yang xi)) ((gene yan) OR (ren yan)) ji wong sam ;*.
