Perhaps you should try some spelling variations:
lang yan » wang yan, wang yang, zhang yan
wong sam » wong sau, wong lai, kong sar
wong siu » wong shiu, kong siu, wong sau
yan ban » can bank, tan bann, wang ban
ban hua » ban bua, tan hua, wang hua
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: lang yan ban hua ren yan jie ((wong sam) OR (wong siu)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan ban hua ren yan jie ((wong sam) or (wong siu)) ;*.
