Perhaps you should try some spelling variations:
tdieu hanh » deu hanh, dieu danh, tiem hanh
hanh doanh » chinh doanh, doanh doanh, kinh doanh
hang doanh » nhung doanh, van doanh, dung doanh
dung dung » ung dung, dung ung, dung dong
dung sinh » duong sinh, dang sinh, dung ninh
sinh toan » tinh toan, hinh toan, minh toan
qua dung » quang dung, su dung, qua song
toan cau » toan cao, toan ban, toan tap

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: toc ((tdieu hanh) OR (dieu hanh)) - ((hanh doanh) OR (hang doanh)) qua dung dung sinh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((tdieu hanh) or (dieu hanh)) - ((hanh doanh) OR (hang doanh)) qua dung dung sinh toan cau~".
• Adding a wildcard symbol may retrieve word variants: toc ((tdieu hanh) or (dieu hanh)) - ((hanh doanh) OR (hang doanh)) qua dung dung sinh toan cau*.
