Perhaps you should try some spelling variations:
chieu sach » chinh sach, chieu sang, chieu xanh
hanh manh » hanh mang, lanh manh, hoang manh
dung cong » dung trong
manh cua » doanh cua, ban cua
cua dung » cua dang, cua dong, qua dung
cong san » cong tac
than cap » khan cap, thanh lap, thanh cac
khoan va » doan va, khoa ma, nhan va

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 sach) OR (chiet tach)) - hanh manh cua dung cong san ((than cap) OR (khoan va))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chiet tach)) - hanh manh cua dung cong san ((than cap) or (khoan va))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chiet tach)) - hanh manh cua dung cong san ((than cap) or (khoan va))*.
