Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
nhung cong » dung cong, thong cong, hang cong
doi chieu » doc hieu, doi chi, ho chieu
trinh cua » trinh luat, trinh quan, trinh luan
tinh cua » sinh cua, tinh chat, tranh cua
cong dan » cong san, cong tan, huong dan
ca cac » cua cac, va cac

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - hanh ((trinh cua) OR (tinh cua)) nhung cong dan ca cac~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - hanh ((trinh cua) OR (tinh cua)) nhung cong dan ca cac*.
