Perhaps you should try some spelling variations:
tong shui » cong shu
wang yao » wang yan, yang yao, gang yao
yang yun » yang jun, tang yun, yang yue
kang min » kan min, tang min, kang minah
gong hui » wang hui, gong si, dong hua
tong hui » wang hui
yang yi » yang di, yang xi, yang jui
lu kang » wu kang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yao ((yang yi) or (yang yun)) lu kang min ((((tong shui) OR (gong hui))) or (tong hui)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yao ((yang yi) OR (yang yun)) lu kang min ((((tong shui) OR (gong hui))) OR (tong hui)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yao ((yang yi) or (yang yun)) lu kang min ((((tong shui) OR (gong hui))) or (tong hui)) ;".
• Adding a wildcard symbol may retrieve word variants: wang yao ((yang yi) or (yang yun)) lu kang min ((((tong shui) OR (gong hui))) or (tong hui)) ;*.
