Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
wang dong » wang yong, wang hong, wang yang
yang hua » wang hua, ying hua, yang jui
yang hui » yang jui, wang hui, yang muxi
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 hui)) wei yang liang ((kong siu) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dong ((yang hua) or (yang hui)) wei yang liang ((kong siu) OR (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang dong ((yang hua) or (yang hui)) wei yang liang ((kong siu) OR (wong siu)) ;*.
