Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hieu manh » chieu xanh, hieu nganh, dieu hanh
hanh tang » hanh trang, anh tang, hanh mang
cua nhung » va nhung
manh toan » thanh toan, anh tuan, tinh toan
ban thanh » ban hanh, ban hang
hoc hieu » hoc thieu, hoc hien, doc hieu
tang cua » mang cua, hang cua, tang luan

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: hoc hieu manh - hanh tang cua nhung cong ((((xuan toan) OR (manh toan))) OR (ban thanh)) cau~.
• Adding a wildcard symbol may retrieve word variants: hoc hieu manh - hanh tang cua nhung cong ((((xuan toan) or (manh toan))) or (ban thanh)) cau*.
