Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu xanh
chieu sang » chieu xanh, hieu lang, nhieu tang
cua nhung » va nhung
anh manh » lanh manh, anh anh, anh danh
manh cua » doanh cua, ban cua
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan cao » toan ban, toan tap

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 sach) OR (chieu sang)) - anh manh cua nhung ((cong dan) OR (cong tan)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sach) or (chieu sang)) - anh manh cua nhung ((cong dan) OR (cong tan)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sach) or (chieu sang)) - anh manh cua nhung ((cong dan) OR (cong tan)) toan cao*.
