Perhaps you should try some spelling variations:
chiet tach » chieu sach
dong cong » duong cong, dung cong, dang cong
thanh cac » hanh cac, thanh bac, thanh ca
ho chiet » ho chieu, ho thiet, hoc thiet
cua dong » chua dong, cua cong, cua dang
cong dan » cong san, cong tan, huong dan
than cap » khan cap, thanh lap, than cua

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 chiet tach - ((thanh tung) OR (thanh cong)) cua dong cong dan ((than cap) OR (thanh cac))~.
• Adding a wildcard symbol may retrieve word variants: ho chiet tach - ((thanh tung) or (thanh cong)) cua dong cong dan ((than cap) or (thanh cac))*.
