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

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 chia))) OR (wuhan china)) gene yang jui wong (lai OR laid) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((((yan hua) or (tan chia))) or (wuhan china)) gene yang jui wong (lai OR laid) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((((yan hua) or (tan chia))) or (wuhan china)) gene yang jui wong (lai OR laid) ;*.
