Perhaps you should try some spelling variations:
thanh trung » thanh tung
cho chinh » chon chinh, che chinh, cuoc chinh
trung cap » truong cao, trung tam
thanh cac » hanh cac, thanh bac, thanh ca
thanh lap » thanh san, phan lap, thanh hai
ung cong » dung cong, luong cong, duong cong
cong tan » cong tac, cong san, cong thanh
cap ung » cap dung, cac ung, dap ung

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: cho chinh sach - thanh trung cap ung cong tan ((thanh cac) OR (thanh lap))~.
• Adding a wildcard symbol may retrieve word variants: cho chinh sach - thanh trung cap ung cong tan ((thanh cac) or (thanh lap))*.
