Perhaps you should try some spelling variations:
triet tinh » trieu tinh, trien tinh, trien kinh
hanh doanh » hang doanh, chinh doanh, doanh doanh
dung doanh » dung dan, dung dong
doanh hoan » doanh doanh, doanh khoa, doanh nhan
mon triet » minh triet, bo triet, mao triet
tong dan » tuong dan, thong dan, trong dan
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac
cua han » cua hang, cua nhan, cua phan

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: mon triet tinh - ((((hanh doanh) OR (dung doanh))) OR (doanh hoan)) cua han tong dan than cap~.
• Adding a wildcard symbol may retrieve word variants: mon triet tinh - ((((hanh doanh) or (dung doanh))) or (doanh hoan)) cua han tong dan than cap*.
