Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tieu sach » chieu sach, dien sach, viet sach
hanh manh » hanh mang, lanh manh, hoang manh
cua nhung » va nhung
manh cua » doanh cua, ban cua
van quan » van ban
te sach » toc sach

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) OR (te sach)) - hanh manh cua nhung cong ((anh tuan) OR (van quan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu sach) OR (te sach)) - hanh manh cua nhung cong ((anh tuan) or (van quan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu sach) OR (te sach)) - hanh manh cua nhung cong ((anh tuan) or (van quan)) cau*.
