Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
trung tuan » trung thanh, trung tam, tran tuan
doi chieu » doc hieu, doi chi, ho chieu
huong cua » dung cua
cong danh » cuong danh, cong thanh, cong khanh
cong dan » cong san, cong tan, huong dan
toan ban » van 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: doi chieu sach - hanh ((trung tuan) OR (huong cua)) nhung ((cong danh) OR (cong dan)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - hanh ((trung tuan) or (huong cua)) nhung ((cong danh) OR (cong dan)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - hanh ((trung tuan) or (huong cua)) nhung ((cong danh) OR (cong dan)) toan ban*.
