Perhaps you should try some spelling variations:
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
chuan kao » chuan dato, chuan fa
kao yang » yao yang, tao yang, xiao yang
yang jin » yang jie, yang jun, ying jin
hong hai » shang hai, zhong tai, 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: ((yang yang) OR (wang yang)) dean chuan kao yang jin ((hong hai) OR (dang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) OR (wang yang)) dean chuan kao yang jin ((hong hai) or (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) OR (wang yang)) dean chuan kao yang jin ((hong hai) or (dang hai)) ;*.
