Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
ho chieu » theo chieu, hoc thieu, doi chieu
hanh han » hanh nhan, hanh phan, hanh san
van dung » van dong, xay dung, tin dung
vat dung » va dung, viet dung, mat duong
tan than » tan thanh, tan tran, tam than
ban than » ban thanh, van thanh, ban hang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sach - hanh han ((van dung) or (vat dung)) cong ((tan than) OR (ban than)) ma~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - hanh han ((van dung) OR (vat dung)) cong ((tan than) OR (ban than)) ma.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh han ((van dung) or (vat dung)) cong ((tan than) OR (ban than)) ma".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh han ((van dung) or (vat dung)) cong ((tan than) OR (ban than)) ma*.
