Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
tuan nhung » quan nhung, tuan hung, thuat nhung
nhung cong » dung cong, thong cong, hang cong
doi chieu » doc hieu, doi chi, ho chieu
hanh tam » thanh tam, nhanh tam, hanh tram
tam tuan » tam than, ta tuan, tai tuan
dan than » dan chan, van than, dan toan
ban than » ban thanh, van thanh, ban hang

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 - hanh tam tuan nhung cong ((xuan toan) OR (((dan than) OR (ban than)))) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - hanh tam tuan nhung cong ((xuan toan) or (((dan than) OR (ban than)))) ban~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - hanh tam tuan nhung cong ((xuan toan) or (((dan than) OR (ban than)))) ban*.
