Perhaps you should try some spelling variations:
long thanh » luong thanh, long han, long trinh
wing kang » jin kang, wing ian, wing tan
tan chia » tuan china, than china, can china
tuan hua » tuan vu, yuan hui
yang jin » yang jie, yang jun, ying jin
yang jui » yang judy, yang di, yang xi
tan hua » wang hua, tan puay

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: wing kang ((((tan hua) OR (tan chia))) OR (tuan hua)) gain ((yang jin) OR (yang jui)) long thanh ;~.
• Adding a wildcard symbol may retrieve word variants: wing kang ((((tan hua) or (tan chia))) or (tuan hua)) gain ((yang jin) or (yang jui)) long thanh ;*.
