Abstract: An information appended-amendment method and system. The information appended-amendment method includes the steps of locating erroneous information sent by a sender, amending the sent erroneous information in accordance with the location of the sent erroneous information, sending error amendment information to a receiver, and amending the sent erroneous information received by the receiver from the sender by using the error amendment information. It is possible to make amendments to any erroneous information while refreshing screens of two parties so as to erase any erroneous character completely, or mark any amended content. In this way, users will have better communication experiences.
