Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chieu sach » chinh sach, chiet tach, chieu sang
van thanh » ban thanh
ho chieu » theo chieu, hoc thieu, doi chieu
chinh va » chinh ta, chinh tai, hanh va
chinh vi » chinh viet, chinh tri, chinh tai
van tuan » van quan, van ban, anh tuan

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 chieu sach - hanh ((chinh va) OR (chinh vi)) nhung cong ((van thanh) OR (van tuan)) cau~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh ((chinh va) or (chinh vi)) nhung cong ((van thanh) or (van tuan)) cau*.
