Perhaps you should try some spelling variations:
doanh cua » doanh luan
trong tan » trong quan, trong cac, trong ca
ho trieu » mot trieu, 30 trieu, ho chieu
25 trieu » 30 trieu
dung cua » dung luan, dung cho
tan than » tan thanh, tan tran, ban than
than tap » toan tap, han tap, phan 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: ((ho trieu) OR (25 trieu)) tinh - hanh ((doanh cua) OR (dung cua)) dung trong tan than tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (25 trieu)) tinh - hanh ((doanh cua) or (dung cua)) dung trong tan than tap~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (25 trieu)) tinh - hanh ((doanh cua) or (dung cua)) dung trong tan than tap*.
