Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
thanh tran » thanh trang, thanh toan, thanh tra
tran xuan » tran quang, tran van
xuan hang » xuan hoang, xuan thang, xuan nang
hang cong » dang cong, hang nong, bang cong
thu sach » tu sach, thuat sach, thuoc sach
cong dan » cong san, cong tan, huong dan
than cau » toan cau, phan cau, thanh chau
than cap » khan cap, thanh lap, thanh cac

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: theo ((chieu sach) OR (thu sach)) - thanh tran xuan hang cong dan ((than cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sach) or (thu sach)) - thanh tran xuan hang cong dan ((than cau) OR (than cap))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sach) or (thu sach)) - thanh tran xuan hang cong dan ((than cau) OR (than cap))*.
