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