Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
hua rene » hua ren, juan rene
tang tin » tang tang, ting ting, tang li
tang min » chang min, yang mind, tang li
hong shu » cong shu, tong shui, wong shiu
yan yan » yan yuan, nan yan, yang yang
yan hua » tan hua, ya hua, wang hua
wang » wing, 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 OR wan) yan yan hua rene ((tang tin) OR (((tang min) OR (sang minh)))) hong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) yan yan hua rene ((tang tin) or (((tang min) OR (sang minh)))) hong shu ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) yan yan hua rene ((tang tin) or (((tang min) OR (sang minh)))) hong shu ;*.
