Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
hanh trung » thanh trung, manh trung, danh trung
hanh trang » thanh trung, canh tranh, hanh trinh
doi chieu » doc hieu, doi chi, ho chieu
han cong » phan cong, hang cong, hanh cong
cong tac » cong ty
cap han » cap phan, cap can, cap hay

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: doi chieu sach - ((hanh trung) OR (hanh trang)) cap han cong tac ((toan ban) OR (van ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - ((hanh trung) OR (hanh trang)) cap han cong tac ((toan ban) or (van ban))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - ((hanh trung) OR (hanh trang)) cap han cong tac ((toan ban) or (van ban))*.
