Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu sach » chinh sach, chiet tach, chieu sang
tranh cua » doanh cua, manh cua
dong cong » duong cong, dung cong, dang cong
tran tuan » tran xuan, tran thanh, tranh luan
cua dong » chua dong, cua cong, cua dang
cong tac » cong ty
quang » quan

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - canh tranh cua dong cong tac ((tran tuan) OR (tran quang))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - canh tranh cua dong cong tac ((tran tuan) OR (tran quang))*.
