Perhaps you should try some spelling variations:
gene yang » gene bank
tuan hua » tuan vu, yuan hui
tan chia » tuan china, than china, can china
yang jui » yang judy, yang di, yang xi
jui wong » ji won, jui meng
tan hua » wang hua, tan puay
wang » wing, wan, lang
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 yan ((((tuan hua) OR (tan hua))) OR (tan chia)) gene yang jui wong lai ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan ((((tuan hua) or (tan hua))) or (tan chia)) gene yang jui wong lai ;*.
