Perhaps you should try some spelling variations:
chieu tinh » lieu tinh, chau tinh, kieu tinh
hanh trang » thanh trung, canh tranh, hanh trinh
trang cua » tranh cua, tang cua, trung cua
dang cong » dung cong
cua dang » cua cong, cua ban
cong tac » cong ty
toan cau » toan cao, toan tap, toan tai
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: ho ((chieu tinh) OR (trieu tinh)) - hanh trang cua dang cong tac ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) OR (trieu tinh)) - hanh trang cua dang cong tac ((toan cau) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) OR (trieu tinh)) - hanh trang cua dang cong tac ((toan cau) or (toan ban))*.
