Perhaps you should try some spelling variations:
than china » tuan china, han china, wuhan china
wang yong » wang yang, wang hyoung, wang yan
gene yang » gene bank
yang jui » yang judy, yang di, yang xi
jui wong » ji won, jui meng
yan hua » ya hua, wang hua, tuan hua
tan hua » tuan hua, wang hua, tan chia
lai » laid

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

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