Perhaps you should try some spelling variations:
wang liang » wang yang
yang yang » wang yang, wang yan
hua gene » human gene, a gene, hua ren
yang jae » yang jie, myung jae, yang fan
yang jui » yang judy, yang di, yang xi
yong seo » hong seo, song so, von seo
kong sek » kong weak, kong sar, kong k

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yang) or (wang liang)) ya hua gene ((yang jae) OR (yang jui)) ((yong seo) or (kong sek)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (wang liang)) ya hua gene ((yang jae) OR (yang jui)) ((yong seo) OR (kong sek)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (wang liang)) ya hua gene ((yang jae) OR (yang jui)) ((yong seo) or (kong sek)) ;*".
