Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh hang » thanh hang, hang hang, hanh han
chu xanh » chu manh, chua xang, chuc danh
ca thang » cau thang, ca tang, ca chang
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
than cap » khan cap, thanh lap, thanh cac
hang ca » hang va, nang cao, hang tai

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 ((chu xanh) OR (chieu xanh)) - hanh hang ca thang ((cong dan) OR (cong tan)) than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chieu xanh)) - hanh hang ca thang ((cong dan) or (cong tan)) than cap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chieu xanh)) - hanh hang ca thang ((cong dan) or (cong tan)) than cap*.
