Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
truong cua » truong ca, truong quan, truong cao
trung cap » truong cao, trung tam
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
gian lan » gian lang, gian dan, giang van

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 - thanh ((trung cap) OR (truong cua)) dung ((cong dan) OR (cong tan)) gian lan~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh ((trung cap) or (truong cua)) dung ((cong dan) OR (cong tan)) gian lan~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh ((trung cap) or (truong cua)) dung ((cong dan) OR (cong tan)) gian lan*.
