Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh doanh » hang doanh, chinh doanh, doanh doanh
doanh cua » doanh luan
cong van » cong vang, song van, cong va
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac
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: theo chieu tinh - hanh doanh cua cong ((((cong van) OR (cong tan))) OR (cong san)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - hanh doanh cua cong ((((cong van) OR (cong tan))) or (cong san)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo chieu tinh - hanh doanh cua cong ((((cong van) OR (cong tan))) or (cong san)) toan ban*.
