Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
yang mind » yang cindy, sang minh, tang min
chai tan » chai tam, chai onn
yang jin » yang jie, yang jun, ying jin
hong hai » zhong tai, dang hai, hong tan
wan yan » wang yan, nan yan, wai yan
ka chai » ka chuan, kim chai
yan ka » yang ka, yuan kai

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