Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, dan yang
yang yang » wang yang, wang yan
than daun » than bau, than daem, than days
than data » than death, loan data, can data
yang jin » yang jie, yang jun, ying jin
jin how » john how
how aid » how asia

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang yang ((than daun) OR (than data)) yang jin how aid ;~".
• Adding a wildcard symbol may retrieve word variants: dong yang yang ((than daun) OR (than data)) yang jin how aid ;*.
