Perhaps you should try some spelling variations:
thanh trung » thanh tung
cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh toan
ho trieu » mot trieu, 25 trieu, ho chieu
30 trieu » 25 trieu
van dung » van dong, tin dung
toan tap » toan ban

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((ho trieu) or (30 trieu)) tinh - thanh trung ((van dung) OR (xay dung)) cong manh toan tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho trieu) OR (30 trieu)) tinh - thanh trung ((van dung) OR (xay dung)) cong manh toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) or (30 trieu)) tinh - thanh trung ((van dung) OR (xay dung)) cong manh toan tap".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) or (30 trieu)) tinh - thanh trung ((van dung) OR (xay dung)) cong manh toan tap*.
