Perhaps you should try some spelling variations:
thanh data » than data, thanh dam
wang yang » wang yan, wang liang, wang yanling
van thanh » tran thanh, phan thanh, lam thanh
data yang » apa yang
yang van » yang fan, yang dean, trang van
mind non » mind how, aid non
min hong » amin hong, tin hong, min hyoung

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: wang yang van thanh data yang ((mind non) OR (min hong)) hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang van thanh data yang ((mind non) or (min hong)) hai ;*.
