Perhaps you should try some spelling variations:
thanh trung » thanh tung
nhung cong » dung cong, thong cong, hang cong
trung cap » truong cao, trung tam
cap nhung » cam nhung, vap nhung, dap nhung
cong tan » cong tac, cong san, cong thanh
than cau » toan cau, phan cau, thanh chau
than cap » khan cap, thanh lap, thanh cac

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) OR (30 trieu)) tinh - thanh trung cap nhung cong tan ((than cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((25 trieu) OR (30 trieu)) tinh - thanh trung cap nhung cong tan ((than cau) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ((25 trieu) OR (30 trieu)) tinh - thanh trung cap nhung cong tan ((than cau) or (than cap))*.
