Perhaps you should try some spelling variations:
chieu sach » chinh sach, chieu sang, chieu xanh
thanh tung » thanh cong
hoan thanh » hoang thanh, ban thanh, van thanh
cong hoan » cong hoa, dong hoa, cong san
thanh lap » thanh san, phan lap, thanh hai
cua dung » cua dong, qua dung, cua rung
cua dang » cua cong, cua ban

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) OR (chiet tach)) - thanh tung ((cua dung) OR (cua dang)) cong hoan thanh lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chiet tach)) - thanh tung ((cua dung) OR (cua dang)) cong hoan thanh lap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (chiet tach)) - thanh tung ((cua dung) OR (cua dang)) cong hoan thanh lap*.
