Perhaps you should try some spelling variations:
shang kai » shang hai
wang yap » wang yan, wang yang, wang yue
kim chai » ka chai
chai tan » chai tam, chai onn
yang jin » yang jun, ying jin, shang jin
yang jie » yang di, yang jui, yang xi
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 tan ((yang jin) OR (yang jie)) ((hong hai) OR (shang kai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yap kim chai tan ((yang jin) OR (yang jie)) ((hong hai) or (shang kai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yap kim chai tan ((yang jin) OR (yang jie)) ((hong hai) or (shang kai)) ;*.
