In this case, the first terminal displays a second interface (the second interface is different from the first interface). The first terminal disconnects from the second terminal; and after the first terminal reconnects to the second terminal, the first terminal may send second display data to the second terminal, so that the second terminal displays a third interface correlated with the first interface.
