Perhaps you should try some spelling variations:
shang hai » dang hai, chang ha, zhang han
chai dan » chai onn, chai tam, shi dan
dan ying » dan qing, dan yang, fan ying
ying jin » yang jin, jing ji, yang jie
hong hai » zhong tai, dang hai, hong tan
nan yan » nan ya, wang yan, qian yan
ka chai » ka chuan, kim chai
yan ka » yang ka, yuan kai

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