Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
thanh tung » thanh cong
bang cong » dang cong, bang song, hang cong
ho chieu » theo chieu, hoc thieu, doi chieu
cua bang » chua bang, cua ban, cua dang
ban than » ban thanh, van thanh, ban hang
van than » van thanh, van thang, van tuan

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) OR (thanh tung)) cua bang cong ((ban than) OR (van than)) cau~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((thanh trung) or (thanh tung)) cua bang cong ((ban than) or (van than)) cau*.
