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
quang toan » quang tuan, quang doan, quang hoan
quang tran » quang tuan, quang trung, quang thanh
trang suc » trang phuc, trang thuc, tran duc
suc dung » su dung, duc dung, tuc 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: theo ((chieu xanh) OR (chieu sach)) - hanh trang suc dung trong ((quang toan) OR (quang tran)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - hanh trang suc dung trong ((quang toan) or (quang tran)) tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - hanh trang suc dung trong ((quang toan) or (quang tran)) tap*.
