Perhaps you should try some spelling variations:
wang dong » wang yong, wang hong, wang yang
yang muxi » yang jui, yang xi, yang hui
yang sing » yang using, yang jing, muang sing
yang hua » wang hua, yang hui, ying hua
wei yang » pei yang, wei wang, wei yang's
kong siu » kong eiu, dong sin, kong sar
wong siu » wong shiu, wong sau, wong siew

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: wang dong ((yang hua) OR (yang muxi)) wei yang sing ((kong siu) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dong ((yang hua) or (yang muxi)) wei yang sing ((kong siu) OR (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang dong ((yang hua) or (yang muxi)) wei yang sing ((kong siu) OR (wong siu)) ;*.
