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

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 ((((yong seo) OR (song so))) 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 ((((yong seo) OR (song so))) 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 ((((yong seo) OR (song so))) or (kong sek)) ;*".
