Perhaps you should try some spelling variations:
thanh hung » thanh huong, thanh tung, thanh trung
tuan phung » tuan hung, tuan phong, tran phuong
mot trieu » mot chieu, mot tri, mon triet
hung tuan » hung tran, quang tuan, trung tuan
30 trieu » 25 trieu
cong tac » cong ty
than cau » toan cau, phan cau, than cap

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: ((mot trieu) OR (30 trieu)) tinh - thanh hung tuan phung ((cong san) OR (cong tac)) than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot trieu) or (30 trieu)) tinh - thanh hung tuan phung ((cong san) OR (cong tac)) than cau~".
• Adding a wildcard symbol may retrieve word variants: ((mot trieu) or (30 trieu)) tinh - thanh hung tuan phung ((cong san) OR (cong tac)) than cau*.
