Perhaps you should try some spelling variations:
hanh doanh » chinh doanh, doanh doanh, kinh doanh
hang doanh » nhung doanh, van doanh, dung doanh
nhan hung » nhanh hung, phan hung, nhan ung
hung cong » nhung cong, hung cuong, phung cong
hoc dieu » hoc thieu, hoc hien
cong dan » cong san, cong tan, huong dan
gian cau » gian chau, gian cac, gian cam

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: "hoc dieu hanh - ((hanh doanh) OR (hang doanh)) nhan hung cong dan gian cau~".
• Adding a wildcard symbol may retrieve word variants: hoc dieu hanh - ((hanh doanh) OR (hang doanh)) nhan hung cong dan gian cau*.
