Perhaps you should try some spelling variations:
chieu sach » chinh sach, chieu sang, chieu xanh
trung tuan » trung thanh, trung tam, truong thanh
tran tuan » tran xuan, tran quang, tran thanh
hung cong » nhung cong, hung cuong, phung cong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
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 ((chiet tach) OR (chieu sach)) - thanh ((trung tuan) OR (tran tuan)) hung cong dan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chiet tach) or (chieu sach)) - thanh ((trung tuan) OR (tran tuan)) hung cong dan than cap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chiet tach) or (chieu sach)) - thanh ((trung tuan) OR (tran tuan)) hung cong dan than cap*.
