Perhaps you should try some spelling variations:
hanh doanh » hang doanh, chinh doanh, doanh doanh
nhung cong » thong cong, hang cong, nhung don
hien xanh » hien hanh, hien nhanh, chieu xanh
doanh cua » doanh luan
dung cong » dung trong
tan han » tan nhan, tran han, tan van
han tu » phan tu, hanh tu, ban tu

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 xanh) OR (dieu hanh)) - hanh doanh cua ((nhung cong) OR (dung cong)) tan han tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (dieu hanh)) - hanh doanh cua ((nhung cong) OR (dung cong)) tan han tu~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (dieu hanh)) - hanh doanh cua ((nhung cong) OR (dung cong)) tan han tu*.
