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