Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, yang yang
yang than » yang dean, yang fan
than data » than death, loan data, can data
data yang » apa yang
dan yang » daun yang, tan yang, wang yang
mind how » aid how
tin hong » tan hong, kia hong, thi hong

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 (dan yang)) yang than data yang ((mind how) OR (tin hong)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) OR (dan yang)) yang than data yang ((mind how) or (tin hong)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong yang) OR (dan yang)) yang than data yang ((mind how) or (tin hong)) hai ;*.
