Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yao chuan » say chuan, ka chuan
hai chuan » say chuan, ka chuan, tai chun
shang hai » shang kai, dang hai, chang ha
tao yang » yao yang, tan yang, xiao yang
yang tin » yang jin, yang lin, yang jing
hong hai » zhong tai, dang hai, hong tan

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