Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu tach » chiet tach, chieu sach, chiu trach
van dung » van dong, xay dung, tin dung
cong tac » cong ty
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban
anh ban » anh bang, anh bai, anh van
va dung » va duong, vat dung, va ung

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

• Performing a fuzzy search may retrieve terms with similar spellings: theo chieu tach - anh ban ((va dung) OR (van dung)) cong tac ((toan cau) or (toan tap))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu tach - anh ban ((va dung) OR (van dung)) cong tac ((toan cau) OR (toan tap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tach - anh ban ((va dung) OR (van dung)) cong tac ((toan cau) or (toan tap))".
• Adding a wildcard symbol may retrieve word variants: theo chieu tach - anh ban ((va dung) OR (van dung)) cong tac ((toan cau) or (toan tap))*.
