Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hieu lang » chieu sang, hieu quang, nhieu tang
canh tinh » hanh tinh, manh tinh, canh tranh
quang ban » quang binh, quang tuan, quang tran
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan ban » van ban

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 (hieu lang)) - canh tinh quang ban ((cong dan) OR (cong tan)) toan ban~.
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (hieu lang)) - canh tinh quang ban ((cong dan) or (cong tan)) toan ban*.
