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