Perhaps you should try some spelling variations:
hanh doanh » hang doanh, chinh doanh, doanh doanh
hien tinh » khien tinh, thien tinh, bien tinh
doanh cua » doanh luan
tong cong » cong cong, dang cong, tvqg cong
dung cong » dung trong
tan toan » tan tran, tap toan, van toan
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 tinh - hanh doanh cua ((((trong cong) OR (tong cong))) OR (dung cong)) tan toan cao~.
• Adding a wildcard symbol may retrieve word variants: hoc hien tinh - hanh doanh cua ((((trong cong) or (tong cong))) or (dung cong)) tan toan cao*.
