Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
tran manh » tran minh, tran thanh, tran van
theo chu » theo chieu, cho chu, chao chu
chu sach » cau sach, thu sach, chieu sach
mang cua » manh cua, dung cua, ban cua
cong dan » cong san, cong tan, huong dan
than man » than ma, thanh san, than phan

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 chu sach - hanh mang cua nhung cong dan ((than man) OR (tran manh))~.
• Adding a wildcard symbol may retrieve word variants: theo chu sach - hanh mang cua nhung cong dan ((than man) or (tran manh))*.
