Perhaps you should try some spelling variations:
wei wang » wei yang, wen wang, wei shang
wang dan » wang yan, wang ban, wang yidan
wong sam » wong sau, wong lai, kong sar
wong siu » wong shiu, kong siu, wong sau
dan hua » tan hua, wang hua, dong hua
hua ren » hua chen
yan jiu » yang jie, yang jin, pang jiu

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wei wang dan hua ren yan jiu ((wong sam) OR (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wei wang dan hua ren yan jiu ((wong sam) OR (wong siu)) ;*.
