Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
manh hung » anh huong
hung cua » huong cua, chung cua, khung cua
cua hang » cua dang, cua nhung, cua cong
cong dan » cong san, cong tan, huong dan
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: hoc ((chieu xanh) OR (chieu tinh)) - manh hung cua hang ((cong dan) OR (cong tac)) toan tap~.
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu tinh)) - manh hung cua hang ((cong dan) or (cong tac)) toan tap*.
