Perhaps you should try some spelling variations:
kang minah » sang minh
dong yang » dong hoang, wang yang, yang yang
yang minh » sang minh, yang mind, anh minh
hua rene » hua ren, juan rene
song min » song ming, gong min, jong min
yang ka » yang fan, yang yao
ka hua » ya hua, ka chuan

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: dong yang ka hua rene ((yang minh) OR (((song min) OR (kang minah)))) cong shu ;~.
• Adding a wildcard symbol may retrieve word variants: dong yang ka hua rene ((yang minh) or (((song min) or (kang minah)))) cong shu ;*.
