Network information propagation method and system thereof

A network information propagation method comprises the following steps: constructing a virtual user and setting attribute information for the virtual user; initiating a request of establishing a friend relation through the virtual user so as to associate an actual user; according to the attribute information of the virtual user, acquiring relevant network information; according to the established friend relation, outputting the network information to the actual user associated with the network information, or/and receiving the network information submitted by the actual user. In the network information propagation method and the system, through constructing the virtual user and establishing the friend relation, a lot of actual users are associated with the virtual users; the attribute information of the virtual user is combined so as to acquire the network information; the network information is output to the actual user associated with the network information. Therefore, possibility for the actual user to get interest is greatly increased and pertinency is strong.
