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, tan yi, yin yi
yan zi » yan zhi, yuan zi
ban zi » ban ji
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 (ban zi)))) 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 (ban zi)))) hua ren ((kang minh) OR (sang minh)) long shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yi) or (((yan zi) or (ban zi)))) hua ren ((kang minh) OR (sang minh)) long shu ;*.
