Perhaps you should try some spelling variations:
wang qian » wang qiao, wang qin, wang liang
wong shiu » wong siu, cong shu, wong sau
wang lin » wang qin, yang lin, wang limin
san minh » sang minh, tuan minh, anh minh
gong hui » tong hui, tong shui, wang hui
wang li » wang lei, tang li, wang di
li san » di san, li lan, li nan

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 qian ((wang lin) OR (wang li)) li san minh ((((wong shiu) OR (song shin))) OR (gong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang qian ((wang lin) or (wang li)) li san minh ((((wong shiu) OR (song shin))) or (gong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang qian ((wang lin) or (wang li)) li san minh ((((wong shiu) OR (song shin))) or (gong hui)) ;*.
