Perhaps you should try some spelling variations:
thanh trung » thanh tung
cong thanh » dong thanh, cong trinh, truong thanh
trung cua » truong cua, trung tuan, trung cap
25 trieu » 30 trieu
cua bang » chua bang, cua ban, cua dang
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong ty
toan cau » toan cao, toan ban, toan 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: 25 trieu tinh - thanh trung cua bang ((cong dan) OR (((cong tan) OR (cong thanh)))) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "25 trieu tinh - thanh trung cua bang ((cong dan) or (((cong tan) OR (cong thanh)))) toan cau~".
• Adding a wildcard symbol may retrieve word variants: 25 trieu tinh - thanh trung cua bang ((cong dan) or (((cong tan) OR (cong thanh)))) toan cau*.
