Perhaps you should try some spelling variations:
chiet tach » chieu sach
hanh doanh » chinh doanh, doanh doanh, kinh doanh
hang doanh » nhung doanh, van doanh, dung doanh
ho chiet » ho chieu, ho thiet, hoc thiet
ban cong » bang cong, van cong, phan cong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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: "ho chiet tach - ((hanh doanh) OR (hang doanh)) cua ban cong dan than cao~".
• Adding a wildcard symbol may retrieve word variants: ho chiet tach - ((hanh doanh) OR (hang doanh)) cua ban cong dan than cao*.
