Perhaps you should try some spelling variations:
thieu tinh » trieu tinh, chieu tinh, thien tinh
hoc thieu » toc thieu, hoc hien
chinh sua » chinh su, chinh cua, chinh luan
sua nhung » cua nhung, qua nhung, chua nhung
cong tac » cong ty
toan cau » toan cao, toan ban, toan tai
toan tap » toan 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: hoc thieu tinh - hanh chinh sua nhung ((cong tac) OR (cong san)) ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu tinh - hanh chinh sua nhung ((cong tac) or (cong san)) ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu tinh - hanh chinh sua nhung ((cong tac) or (cong san)) ((toan cau) OR (toan tap))*.
