Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
yang mind » yang cindy, yang jin, tang min
hong hai » shang hai, zhong tai, dang hai
chang ha » chang mae
ka chai » ka chuan, kim chai
chai du » chaine du
yan ka » yang ka, yuan kai
wang » wing, wan, 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 yan ka chai du ((yang mind) OR (sang minh)) ((hong hai) OR (chang ha)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ka chai du ((yang mind) OR (sang minh)) ((hong hai) or (chang ha)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ka chai du ((yang mind) OR (sang minh)) ((hong hai) or (chang ha)) ;*.
