Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
thanh tran » thanh trang, thanh toan, thanh tra
van nhung » van nhuong, van hung, van phung
ho chieu » theo chieu, hoc thieu, doi chieu
choi dan » hoi dan, hoa dan, hoc dan
toan cao » toan ban
toan tap » toan ban

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 chieu sach - thanh tran ((van nhung) OR (va nhung)) choi dan ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh tran ((van nhung) OR (va nhung)) choi dan ((toan cao) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh tran ((van nhung) OR (va nhung)) choi dan ((toan cao) or (toan tap))*.
