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

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