Perhaps you should try some spelling variations:
chinh quan » chinh luan, chinh quyen, chinh ngan
chieu sach » chinh sach, chiet tach, chieu sang
hieu manh » chieu xanh, hieu nganh, dieu hanh
quan ban » quang ban, qua ban, quan van
ban hang » ngan hang
tuan tap » toan tap, tuyen tap, toan tai
tuan tai » toan tai, quan tai, tan tai

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 ((hieu manh) OR (chieu sach)) - hanh chinh quan ban hang va ((tuan tap) OR (tuan tai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chieu sach)) - hanh chinh quan ban hang va ((tuan tap) OR (tuan tai))~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu sach)) - hanh chinh quan ban hang va ((tuan tap) OR (tuan tai))*.
