Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
trung tuan » trung thanh, trung tam, tran tuan
doi chieu » doc hieu, doi chi, ho chieu
thanh lap » thanh san, phan lap, thanh van
thanh hai » thanh phan, thanh hoa, thanh san
cong ban » cong bang, cong san, cong tan

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: doi chieu sach - thanh ((dung cho) OR (trung tuan)) trong cong ban ((thanh lap) OR (thanh hai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - thanh ((dung cho) or (trung tuan)) trong cong ban ((thanh lap) OR (thanh hai))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - thanh ((dung cho) or (trung tuan)) trong cong ban ((thanh lap) OR (thanh hai))*.
