Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, yang yang
than days » than daem, than data
shang hai » shang kai, chang ha, hong hai
yang fan » zhang fan, yang dean, yang yang
fan than » van thanh
yang jin » yang jie, yang jun, shang jin
ying jin » jing ji, yang jie

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: dong yang fan than days ((yang jin) OR (ying jin)) ((shang hai) OR (dang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang fan than days ((yang jin) OR (ying jin)) ((shang hai) or (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong yang fan than days ((yang jin) OR (ying jin)) ((shang hai) or (dang hai)) ;*.
