Perhaps you should try some spelling variations:
kang ming » zhang ming, kang minah, kan min
wang yao » wang yan, yang yao, wang tao
gang yao » yang yao, wang yan, ganga ya
kong hui » tong hui, wang hui, feng hui
gong hui » tong hui, tong shui, wang hui
yang vi » yang di, yang xi, yang yi
vi ai » vi a, ai ai, ii ai

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 yao) OR (gang yao)) yang vi ai ((kang ming) OR (kian ming)) ((kong hui) OR (gong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yao) or (gang yao)) yang vi ai ((kang ming) OR (kian ming)) ((kong hui) or (gong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yao) or (gang yao)) yang vi ai ((kang ming) OR (kian ming)) ((kong hui) or (gong hui)) ;*.
