Perhaps you should try some spelling variations:
chiet tach » chieu sach
thanh dung » thanh duong, thanh tung, thanh hung
hang cong » dang cong, hang nong, bang cong
cong toan » cong tan, cong hoan, cong tuan
dung cua » dung luan, dung cho
cua hang » cua dang, cua nhung, cua cong
tao cao » toan cao

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 ((chiet tach) OR (chinh sach)) - thanh dung cua hang cong toan ((tao cao) OR (bao cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chiet tach) or (chinh sach)) - thanh dung cua hang cong toan ((tao cao) OR (bao cao))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chiet tach) or (chinh sach)) - thanh dung cua hang cong toan ((tao cao) OR (bao cao))*.
