Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh tranh » canh tranh, hanh trinh, hanh trang
cua hang » cua dang, cua nhung, cua ban
than cap » thanh lap, thanh cac, than cua
khan cap » khan ap, khoan cam, phan cac

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 xanh - hanh tranh ((cua hang) OR (cua cong)) cong ty ((than cap) OR (khan cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - hanh tranh ((cua hang) OR (cua cong)) cong ty ((than cap) or (khan cap))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - hanh tranh ((cua hang) OR (cua cong)) cong ty ((than cap) or (khan cap))*.
