Perhaps you should try some spelling variations:
gang minh » kang minah, anh minh, gong min
yang yang » wang yang, wang yan
sang minh » kang minah, anh minh, song min
yan yang » yao yang, dan yang, tan yang
long shu » cong shu, tong shui, long du
xi i » xi ai, i i, ii i
wang » wing, wan, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yan yang) OR (yang yang)) xi i ((gang minh) or (sang minh)) long shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan yang) OR (yang yang)) xi i ((gang minh) OR (sang minh)) long shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yang) OR (yang yang)) xi i ((gang minh) or (sang minh)) long shu ;*".
