Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
wang yang » wang yan, wang liang, wang yanling
chuan kao » chuan dato, chuan fa
shang hai » shang kai, dang hai, chang ha
ka chuan » say chuan, hai chuan, ka chai
yang jin » yang jie, yang jun, ying jin
yang ka » yang fan, yang yao

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 ka chuan kao ((yang jin) OR (yang liang)) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang ka chuan kao ((yang jin) or (yang liang)) shang hai ;*.
