chieu sach » chinh sach, chiet tach, chieu sang
tac dung » sach dung, xay dung, tin dung
cong dan » cong san, cong tan, huong dan

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu xanh) OR (chieu sach)) - hanh chinh ((ta dung) or (tac dung)) cong dan toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - hanh chinh ((ta dung) OR (tac dung)) cong dan toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - hanh chinh ((ta dung) or (tac dung)) cong dan toan ban".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - hanh chinh ((ta dung) or (tac dung)) cong dan toan ban*.
