Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
hanh mang » nhanh mang, hanh trang, nhanh lang
dung cong » dung trong
mang cua » manh cua, dung cua, ban cua
cua dung » cua dang, cua dong, qua dung
cong dan » cong san, cong tan, huong dan
than cap » khan cap, thanh lap, thanh cac
phan dau » phan tu, hang dau

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 mang cua dung cong dan ((than cap) OR (phan dau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - hanh mang cua dung cong dan ((than cap) or (phan dau))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - hanh mang cua dung cong dan ((than cap) or (phan dau))*.
