Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
chia gene » chia wen, china gender
min hong » amin hong, tin hong, min hyoung
tan chia » tuan china, than china, can china
yang jin » yang jie, yang jun, ying jin
yang jui » yang judy, yang di, yang xi
wong sau » wong sam, wong siu, wong shiu
yang yi » yang di, yang xi

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) OR (min hong)) tan chia gene ((((yang jin) OR (yang jui))) OR (yang yi)) wong sau ;~.
• Adding a wildcard symbol may retrieve word variants: ((lang hyoung) or (min hong)) tan chia gene ((((yang jin) or (yang jui))) or (yang yi)) wong sau ;*.
