Perhaps you should try some spelling variations:
shang hai » shang kai, chang ha, zhang han
chai dan » chai onn, chai tam, shi dan
dan yang » daun yang, tan yang, wang yang
yang jun » yang jui, pang jun, yang jin
hong hai » zhong tai, hong tan, hong a
ka chai » ka chuan, kim chai
yan ka » yang ka, yuan kai
wang » wing, wan, lang

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