Perhaps you should try some spelling variations:
dung phuong » dung thuong, bang phuong, dung chung
theo chieu » theo tieu, theo chu, thi chieu
hanh doanh » hang doanh, chinh doanh, doanh doanh
ho chieu » hoc thieu, doi chieu, mot chieu
doanh va » doan va, doanh tai, doanh cua
van toan » van tuan, van tan, van thanh
van quan » van ban
va dung » van dung, va duong, vat dung

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: ((theo chieu) OR (ho chieu)) tinh - hanh doanh va dung phuong ((van toan) OR (van quan)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (ho chieu)) tinh - hanh doanh va dung phuong ((van toan) or (van quan)) ban~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (ho chieu)) tinh - hanh doanh va dung phuong ((van toan) or (van quan)) ban*.
