Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh manh » hanh mang, lanh manh, hoang manh
cua nhung » va nhung
manh toan » thanh toan, anh tuan, tinh toan
theo chu » theo chieu, cho chu, chao chu
chu sach » cau sach, thu sach, chieu sach
manh cua » doanh cua, ban cua
dan than » dan chan, ban than, van than
ban hang » ngan hang

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