Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
nhanh dong » hanh dong, nhanh chong, anh dong
cua nhung » va nhung
dong cua » dung cua, cong cua, huong cua
cong tac » cong ty
toan tap » toan 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: theo ((chieu xanh) OR (chieu sach)) - nhanh dong cua nhung ((huong dan) OR (cong tac)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - nhanh dong cua nhung ((huong dan) or (cong tac)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - nhanh dong cua nhung ((huong dan) or (cong tac)) toan tap*.
