Perhaps you should try some spelling variations:
cheng tan » cheng han, chen tan, cheng guan
wang yang » wang yan, wang liang, wang yanling
wing tan » wing ian, liang tan, hong tan
kai hong » bai chong, hai phong, wai hoong
hong sau » wong sau, hong paul, kong sar
yang xi » yang di, yang yi, yang jui
tan kai » tan kah, yuan kai

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 tan ((((yang judy) OR (wang yang))) OR (yang xi)) cheng tan kai hong sau ;~.
• Adding a wildcard symbol may retrieve word variants: wing tan ((((yang judy) or (wang yang))) or (yang xi)) cheng tan kai hong sau ;*.
