Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
thanh cau » thanh chau, thanh mau, nhanh cau
chi tach » chiu trach, chiet tach, chi thanh
ca nhung » cua nhung, cam nhung, va nhung
cam hung » cac chung, van hung, mai hung
cong ban » cong bang, cong san, cong tan
doi chi » doi khi

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: doi chi tach - hanh chinh ((ca nhung) OR (((cam hung) OR (cam nang)))) cong ban thanh cau~.
• Adding a wildcard symbol may retrieve word variants: doi chi tach - hanh chinh ((ca nhung) or (((cam hung) or (cam nang)))) cong ban thanh cau*.
