Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, yang yang
than daem » than data, than deep, thanh dam
than days » than data
shang hai » shang kai, dang hai, chang ha
chang mae » chang ha, changes made
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: dong yang ka ((than daem) OR (than days)) yang jin ((shang hai) OR (chang mae)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang ka ((than daem) OR (than days)) yang jin ((shang hai) or (chang mae)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong yang ka ((than daem) OR (than days)) yang jin ((shang hai) or (chang mae)) ;*.
