Perhaps you should try some spelling variations:
shang kai » shang hai
wang yap » wang yan, wang yang, wang yue
kim chai » ka chai
chai dan » chai onn, chai tam, shi dan
dan yang » daun yang, tan yang, wang yang
yang jin » yang jie, yang jun, ying jin
hong hai » shang hai, zhong tai, dang hai

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 yap kim chai dan yang jin ((hong hai) OR (shang kai)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yap kim chai dan yang jin ((hong hai) or (shang kai)) ;*.
