Perhaps you should try some spelling variations:
chinh quyet » chinh huyen, thanh quyet, chinh truyen
chieu sach » chinh sach, chiet tach, chieu sang
van huong » van chuong, van phuong, ban huong
ho chieu » theo chieu, hoc thieu, doi chieu
dan toan » van toan, manh toan, xuan toan
dan than » dan chan, ban than, van than

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 - hanh ((chinh quyet) OR (chinh quyen)) van huong ((dan toan) OR (dan than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh ((chinh quyet) OR (chinh quyen)) van huong ((dan toan) or (dan than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh ((chinh quyet) OR (chinh quyen)) van huong ((dan toan) or (dan than)) cau*.
