Perhaps you should try some spelling variations:
thanh trung » thanh tung
dang luong » nang luong, dung luong, hang luong
hieu manh » chieu xanh, hieu nganh, dieu hanh
trung cap » truong cao, trung tam
luong bai » luong tai, cuong bai, luong bac
cap dang » cao dang, cac dang, cap bang
toan cau » toan cao, toan tap, toan tai
toan ban » van ban

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 ((hieu manh) OR (chinh sach)) - thanh trung cap dang luong bai ((toan cau) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chinh sach)) - thanh trung cap dang luong bai ((toan cau) or (toan ban))*.
