Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
doan tien » doan thien, doanh tien, toan tien
trinh tu » trinh ky, trinh do
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
toan cau » toan cao, toan ban, toan tap
tu dung » tuc dung, tu duong, su dung

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: doan tien thinh - hanh trinh tu dung ((cong tan) OR (cong tac)) toan cau~.
• Adding a wildcard symbol may retrieve word variants: doan tien thinh - hanh trinh tu dung ((cong tan) or (cong tac)) toan cau*.
