Perhaps you should try some spelling variations:
hoan chinh » hanh chinh, hoa hinh
nhung cong » dung cong, thong cong, hang cong
hoa chinh » hoa hinh, hoc chinh, hoa thinh
trung cap » truong cao, trung tam
cong dan » cong san, cong tan, huong dan
dan chan » dan gian, dan ca, van chat
chan cau » phan cau, can cau, chinh cau

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: ((hoa chinh) OR (hoan chinh)) sach - thanh ((dung luan) OR (trung cap)) nhung cong dan chan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoa chinh) OR (hoan chinh)) sach - thanh ((dung luan) or (trung cap)) nhung cong dan chan cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoa chinh) OR (hoan chinh)) sach - thanh ((dung luan) or (trung cap)) nhung cong dan chan cau*.
