Perhaps you should try some spelling variations:
kang minh » kang minah, anh minh, kan min
sang minh » kang minah, anh minh, song min
long shu » cong shu, tong shui, long du
hua ren » hua chen
yan yi » yang yi, yin yi
yan zi » yan zhi, yuan zi, ban zi
tan yi » tang yi, tan li, tan ying
wang » wing, wan, lang

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 ((((yan yi) OR (yan zi))) OR (tan yi)) hua ren ((kang minh) OR (sang minh)) long shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yan yi) or (yan zi))) or (tan yi)) hua ren ((kang minh) OR (sang minh)) long shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yan yi) or (yan zi))) or (tan yi)) hua ren ((kang minh) OR (sang minh)) long shu ;*.
