Perhaps you should try some spelling variations:
chinh cua » chinh ca, chinh sua, hinh cua
cong tinh » cong trinh, cong thanh, trong tinh
cong vinh » cong trinh, trong vinh, cong viec
long tinh » trong tinh, luong tin, dong tin
chi tach » chiu trach, chiet tach, chi thanh
cua dung » cua dang, cua dong, qua dung
toan cau » toan cao, toan ban, toan tap
doi chi » doi khi

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: doi chi tach - hanh chinh cua dung ((((cong tinh) OR (cong vinh))) OR (long tinh)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi tach - hanh chinh cua dung ((((cong tinh) OR (cong vinh))) or (long tinh)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: doi chi tach - hanh chinh cua dung ((((cong tinh) OR (cong vinh))) or (long tinh)) toan cau*.
