Perhaps you should try some spelling variations:
theo chieu » ho chieu, theo chu, thi chieu
hanh dung » thanh dung, anh dung, hanh dong
luan dang » luan nang, luan danh, luan dong
dang cong » dung cong
cong dan » cong san, cong tan, huong dan
than cau » phan cau, than cap, thanh chau
toan cau » toan cao, toan ban, toan tap

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: ((theo chieu) OR (theo tieu)) xanh - hanh dung luan dang cong dan ((than cau) OR (toan cau))~.
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (theo tieu)) xanh - hanh dung luan dang cong dan ((than cau) or (toan cau))*.
