Perhaps you should try some spelling variations:
luan chung » luan chinh
cong thanh » dong thanh, cong trinh, truong thanh
hanh dung » thanh dung, anh dung, hanh dong
hoc tien » hoc tieng, hoc hien, hoc vien
tien anh » tieng anh, tien manh, dien anh
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong ty
toan ban » van 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: hoc tien anh - hanh dung luan chung ((cong dan) OR (((cong tan) OR (cong thanh)))) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc tien anh - hanh dung luan chung ((cong dan) or (((cong tan) OR (cong thanh)))) toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc tien anh - hanh dung luan chung ((cong dan) or (((cong tan) OR (cong thanh)))) toan ban*.
