Perhaps you should try some spelling variations:
hien hanh » dieu hanh
doanh ban » doanh bat, doanh van, doanh nhan
quan hanh » quan thanh, quang thanh, quang khanh
hanh cong » thanh cong, hang cong, hanh dong
canh dan » canh van, thanh dan, cac dan
sanh dan » sach danh, sinh danh, thanh dan
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
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: hoc hien hanh - ((doanh ban) OR (((canh dan) OR (sanh dan)))) quan hanh cong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: hoc hien hanh - ((doanh ban) or (((canh dan) or (sanh dan)))) quan hanh cong dan toan cau*.
