Perhaps you should try some spelling variations:
canh doanh » hanh doanh, chinh doanh, doanh doanh
doanh luan » doanh nhan
hien manh » hien hanh, tien manh, hieu manh
tong cong » trong cong, dung cong, dang cong
cong cong » cong dong, trong cong, dung cong
manh toan » thanh toan, anh tuan, tinh toan
van than » van thanh, van thang, van tuan

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 manh - canh doanh luan ((tong cong) OR (cong cong)) ((manh toan) OR (van than)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien manh - canh doanh luan ((tong cong) OR (cong cong)) ((manh toan) or (van than)) cao~".
• Adding a wildcard symbol may retrieve word variants: hoc hien manh - canh doanh luan ((tong cong) OR (cong cong)) ((manh toan) or (van than)) cao*.
