Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
hanh doanh » chinh doanh, doanh doanh, kinh doanh
hang doanh » nhung doanh, van doanh, dung doanh
ho chieu » theo chieu, hoc thieu, doi chieu
dong bai » dong tai, dong bac, dong ban
tap cau » tap cac, tao cau, ta cau

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 chieu sach - ((hanh doanh) OR (hang doanh)) cua cong dong bai tap cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((hanh doanh) OR (hang doanh)) cua cong dong bai tap cau*.
