Perhaps you should try some spelling variations:
dong yang » dong hoang, yang yang, dan yang
wang yang » wang yan, wang liang, wang yanling
shang hai » shang kai, chang ha, hong hai
than tan » tan tan, othman tan, than rain
tan yang » dan yang, tan ying, tan yong
yang jin » yang jie, yang jun, ying jin
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: ((dong yang) OR (wang yang)) dean than tan yang jin ((shang hai) OR (dang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) OR (wang yang)) dean than tan yang jin ((shang hai) or (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong yang) OR (wang yang)) dean than tan yang jin ((shang hai) or (dang hai)) ;*.
