Perhaps you should try some spelling variations:
yan tuan » yan guan, yan yuan, anh tuan
tuan hua » tan hua, tuan vu, yuan hui
wong sam » wong sau, wong lai, von sam
wong siu » wong shiu, kong siu, wong sau
wan yan » wang yan, nan yan, wai yan
hua ren » hua chen
yan jie » yang jie, yan jiu, yang jin

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: wan yan tuan hua ren yan jie ((((wong sam) OR (kong sar))) OR (wong siu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan tuan hua ren yan jie ((((wong sam) or (kong sar))) or (wong siu)) ;*.
