Perhaps you should try some spelling variations:
danh bac » doanh bac, danh bat, dan bac
hoc vien » hoc viet, hoc vi
canh tac » canh tay, canh giac, cong tac
danh cac » dinh cac, danh ca, hanh cac
danh tac » doanh tai, danh thuc, danh tu
hien nam » phien nam, hien nay, vien nam
bac va » ban va, bac ha, bao va
tac xa » tuc xa, tac da
tac va » tac da, tuc va, tac ha

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((( danh ((tac va) or (tac xa)) hoc hien nam ) or ( danh bac va hoc hien nam ))) or ( danh cac ((van hoc) or (van hoa)) hien nam ))) or ( ((danh tac) OR (canh tac)) dan ((hoc vien) or (hoc tieng)) nam ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((( danh ((tac va) OR (tac xa)) hoc hien nam ) OR ( danh bac va hoc hien nam ))) OR ( danh cac ((van hoc) OR (van hoa)) hien nam ))) OR ( ((danh tac) OR (canh tac)) dan ((hoc vien) OR (hoc tieng)) nam ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((( danh ((tac va) or (tac xa)) hoc hien nam ) or ( danh bac va hoc hien nam ))) or ( danh cac ((van hoc) or (van hoa)) hien nam ))) or ( ((danh tac) OR (canh tac)) dan ((hoc vien) or (hoc tieng)) nam ))*".
