Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
yang muxi » yang jui, yang xi, yang mu
tong shui » tong hui, gong hui
zhang zhi » zhong zhi, wang zhi, zhang wei
wing dan » king dan, wang dan, wing ian
yang hui » yang jui, wang hui, zhang hui
li sang » le sang, li gang, li san

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: wing dan ((yang hui) OR (yang muxi)) li sang minh ((((tong shui) OR (cong shu))) OR (zhang zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing dan ((yang hui) OR (yang muxi)) li sang minh ((((tong shui) or (cong shu))) or (zhang zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing dan ((yang hui) OR (yang muxi)) li sang minh ((((tong shui) or (cong shu))) or (zhang zhi)) ;*.
