Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tieu sach » chieu sach, dien sach, te sach
ganh nang » anh nang, nganh nong, van nang
cua nhung » va nhung
anh tang » anh bang, anh dang, anh nang
cong dan » cong san, cong tan, huong dan
tai cao » thai cao, tao cao, tai cac
tai sao » tai san

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 tieu sach - ((anh tang) OR (ganh nang)) cua nhung cong dan ((tai cao) OR (tai sao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu sach - ((anh tang) or (ganh nang)) cua nhung cong dan ((tai cao) OR (tai sao))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu sach - ((anh tang) or (ganh nang)) cua nhung cong dan ((tai cao) OR (tai sao))*.
