Perhaps you should try some spelling variations:
triet tinh » trieu tinh, trien tinh, trien kinh
hanh doanh » hang doanh, chinh doanh, doanh doanh
doanh luan » doanh nhan
luan hang » luan nang, luan han, luan hung
hang cong » dang cong, hang nong, bang cong
va triet » va thiet, va trien, ve triet
dan toan » van toan, dan than, manh 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: va triet tinh - hanh doanh luan hang cong ((dan toan) OR (van than)) cau~.
• Adding a wildcard symbol may retrieve word variants: va triet tinh - hanh doanh luan hang cong ((dan toan) or (van than)) cau*.
