Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
than china » tuan china, han china, wuhan china
gene yang » gene bank
tan chia » tuan china, can china, dan china
yang jui » yang judy, yang di, yang xi
jui wong » ji won, jui meng
yan hua » tan hua, ya hua, wang hua
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: lang hyoung ((((yan hua) OR (tan chia))) OR (than china)) gene yang jui wong lai ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((((yan hua) or (tan chia))) or (than china)) gene yang jui wong lai ;*.
