Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chieu sach » chinh sach, chiet tach, chieu sang
doanh cua » doanh luan
ho chieu » theo chieu, hoc thieu, doi chieu
manh cua » ban cua
cong san » cong tac
thanh ca » thanh cha, thanh cac, thanh ha

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 ((manh cua) OR (doanh cua)) nhung cong san ((thanh ca) OR (doan va))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh ((manh cua) OR (doanh cua)) nhung cong san ((thanh ca) or (doan va))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh ((manh cua) OR (doanh cua)) nhung cong san ((thanh ca) or (doan va))*.
