Perhaps you should try some spelling variations:
thieu manh » hieu manh, tien manh, trieu minh
chinh quan » chinh luan, chinh quyen, chinh ngan
quan thong » quang thong, quan trong, xuan thong
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
toan cao » toan ban
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: toc thieu manh - hanh chinh quan thong ((cong dan) OR (cong san)) ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc thieu manh - hanh chinh quan thong ((cong dan) OR (cong san)) ((toan cao) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: toc thieu manh - hanh chinh quan thong ((cong dan) OR (cong san)) ((toan cao) or (toan tap))*.
