Perhaps you should try some spelling variations:
chiet tach » chieu sach
cua truong » cua trung, xuan truong, cac truong
xa truong » cac truong
ho chiet » ho chieu, ho thiet, hoc thiet
anh tang » anh bang, anh dang, anh nang
tan dan » tang dan, tan doan, tan van
ban dan » ban hang, ban hanh, ban quan

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 chiet tach - anh tang ((cua truong) OR (xa truong)) cong ((tan dan) OR (ban dan)) ca~.
• Adding a wildcard symbol may retrieve word variants: ho chiet tach - anh tang ((cua truong) or (xa truong)) cong ((tan dan) or (ban dan)) ca*.
