Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
hanh trang » thanh trung, canh tranh, hanh trinh
trang cua » tranh cua, tang cua, trung cua
cua duong » cua dong, cua huong, qua duong
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
than man » than ma, thanh san, tran manh

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: hoc ((chieu xanh) OR (chieu sang)) - hanh trang cua duong ((cong dan) OR (cong tan)) than man~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) OR (chieu sang)) - hanh trang cua duong ((cong dan) or (cong tan)) than man~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) OR (chieu sang)) - hanh trang cua duong ((cong dan) or (cong tan)) than man*.
