Perhaps you should try some spelling variations:
hung thang » cang thang, hung tran
ho chinh » hoc chinh, cho chinh, hoa chinh
vat dung » van dung, viet dung, mat duong
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac
toan cao » toan ban, toan tap
va dung » van dung, va duong, va ung

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: ho chinh sach - hung thang ((va dung) OR (vat dung)) ((cong tan) OR (cong san)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chinh sach - hung thang ((va dung) or (vat dung)) ((cong tan) OR (cong san)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho chinh sach - hung thang ((va dung) or (vat dung)) ((cong tan) OR (cong san)) toan cao*.
