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
cua truong » cua trung, xuan truong, cac truong
cua phuong » cuu phuong, cuc phuong, luan phuong
dong tac » cong tac, dong tai, dong bac
tac than » tac thanh, tam than, tac nhan
than cau » toan cau, phan cau, than cap

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 truong) OR (cua phuong)) dong tac than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - hanh trang ((cua truong) or (cua phuong)) dong tac than cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - hanh trang ((cua truong) or (cua phuong)) dong tac than cau*.
