Perhaps you should try some spelling variations:
liang sudan » liang dan, liang sun
wang liang » wang yang
sudan chen » sudan ch
wen wang » wei wang, chen wang, weng fang
yang jun » yang jui, pang jun, yang jin
wong sam » wong sau, wong lai, kong sar
yang xi » yang yi, yang jui

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: wen wang liang sudan chen ((((((yang xi) OR (yang judy))) OR (yang di))) OR (yang jun)) wong sam ;~.
• Adding a wildcard symbol may retrieve word variants: wen wang liang sudan chen ((((((yang xi) or (yang judy))) or (yang di))) or (yang jun)) wong sam ;*.
