Perhaps you should try some spelling variations:
thanh tung » thanh cong
dung cong » dung trong
chi sach » chinh sach, chieu sach, moi sach
tung cua » trung cua, tuong cua, dung cua
cua dung » cua dang, cua dong, qua dung
cong dan » cong san, cong tan, huong dan
toan cao » toan tap
toan ban » van ban
co sach » bo sach, cuon sach, hoc sach

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 ((chi sach) OR (co sach)) - thanh tung cua dung cong dan ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi sach) OR (co sach)) - thanh tung cua dung cong dan ((toan cao) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doi ((chi sach) OR (co sach)) - thanh tung cua dung cong dan ((toan cao) or (toan ban))*.
