Perhaps you should try some spelling variations:
shang kai » shang hai
wang tan » wang yan, wang dan, wang tao
wang ban » wang yan, wang dan, wang yang
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 tan) OR (wang ban)) kim chai dan yang jin ((hong hai) OR (shang kai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang tan) OR (wang ban)) kim chai dan yang jin ((hong hai) or (shang kai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang tan) OR (wang ban)) kim chai dan yang jin ((hong hai) or (shang kai)) ;*.
