Perhaps you should try some spelling variations:
thuong cong » thong cong, thuong con, thuong dong
hanh trang » thanh trung, canh tranh, hanh trinh
ho chieu » theo chieu, hoc thieu, doi chieu
trang va » tran van, hang va
cong tac » cong ty
toan cau » toan ban, toan tap, toan tai
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: ((ho chieu) OR (theo tieu)) xanh - hanh trang va thuong cong tac ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo tieu)) xanh - hanh trang va thuong cong tac ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo tieu)) xanh - hanh trang va thuong cong tac ((toan cau) OR (toan cao))*.
