Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
qian yan » qian jun, qian yi
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
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: qian yan ka chai dan ying jin ((hong hai) OR (shang hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: qian yan ka chai dan ying jin ((hong hai) or (shang hai)) ;*.
