Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
hanh trang » thanh trung, canh tranh, hanh trinh
trang cua » tranh cua, tang cua, trung cua
cua tong » cua cong, cua dong, cua nong
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
toan cau » 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 xanh) OR (chieu sach)) - hanh trang cua tong ((cong tan) OR (cong tac)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sach)) - hanh trang cua tong ((cong tan) OR (cong tac)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sach)) - hanh trang cua tong ((cong tan) OR (cong tac)) toan cau*.
