Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
yang mind » yang cindy, yang jin, tang min
zhong tai » hong tan, hong hai, zhong zhi
shang hai » shang kai, dang hai, chang ha
wan yang » wang yang, dan yang, tan yang
yang kim » yong kim, kang kim, hyung kim
kim chai » ka chai
chai dan » chai onn, chai tam, shi dan

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: wan yang kim chai dan ((yang mind) OR (sang minh)) ((zhong tai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yang kim chai dan ((yang mind) OR (sang minh)) ((zhong tai) or (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yang kim chai dan ((yang mind) OR (sang minh)) ((zhong tai) or (shang hai)) ;*.
