Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
yang fan » zhang fan, yang yang, yang jin
huan tao » huang tao, chuan kao, huan t'an
tao yang » yao yang, tan yang, xiao yang
yang tin » yang jin, yang lin, yang jing
hong hai » zhong tai, dang hai, hong tan
dean » dewan, jean, den

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 ((yang fan) OR (yang dean)) huan tao yang tin ((hong hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang fan) or (yang dean)) huan tao yang tin ((hong hai) OR (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang fan) or (yang dean)) huan tao yang tin ((hong hai) OR (shang hai)) ;*.
