Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
trung cua » truong cua, trung tuan, dung cua
trung cap » truong cao, trung tam
ho chinh » hoc chinh, cho chinh, hoa chinh
cong tac » cong ty
khan cap » khan ap, khoan cam, phan cac
than cap » thanh lap, thanh cac, than cua

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 chinh sach - hanh ((trung cua) OR (trung cap)) nhung cong tac ((khan cap) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chinh sach - hanh ((trung cua) OR (trung cap)) nhung cong tac ((khan cap) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ho chinh sach - hanh ((trung cua) OR (trung cap)) nhung cong tac ((khan cap) or (than cap))*.
