Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
song minh » song min, song ming, gong min
zhang zhi » zhong zhi, wang zhi, zhang wei
wang dan » wang yan, wang ban, wang yidan
dan guan » gan guan, yan guan, dan sukan
long shu » cong shu, tong shui, long du
hong ghi » zhong zhi, hong g, hong hai
muzi » muni, mezi

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 dan guan muzi li ((song minh) OR (sang minh)) ((long shu) OR (((zhang zhi) OR (hong ghi)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dan guan muzi li ((song minh) OR (sang minh)) ((long shu) or (((zhang zhi) or (hong ghi)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang dan guan muzi li ((song minh) OR (sang minh)) ((long shu) or (((zhang zhi) or (hong ghi)))) ;*.
