Perhaps you should try some spelling variations:
thanh trung » thanh tung
mot trieu » mot chieu, mot tri, mon triet
ho trieu » 25 trieu, 30 trieu, ho chieu
vat dung » van dung, viet dung, mat duong
cong san » cong tac
va dung » van dung, va duong, va ung
san can » san van, ban can, san chang
can cau » van cau, ban cau, ca cau

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 (mot trieu)) tinh - thanh trung ((va dung) OR (vat dung)) cong san can cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (mot trieu)) tinh - thanh trung ((va dung) or (vat dung)) cong san can cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (mot trieu)) tinh - thanh trung ((va dung) or (vat dung)) cong san can cau*.
