and facilitating, by the first terminal, displaying a second message container on top of the background layer, wherein the second message container includes two or more message boxes separate from each other. ### Claim 7 A method for presenting a live broadcasting data stream, comprising: displaying, by a computing device participating in a group session, a group session interface, the group session further including a terminal corresponding to a first user identifier, the first user identifier being a user identifier initiating a live broadcast among participators of the group session and collecting a live broadcasting data stream to be sent to a server, wherein the server determines a network state of the computing device; receiving, by the computing device, the live broadcasting data stream in response to the server's determining that the network state of the computing terminal is a network other than a mobile data network; and receiving, by the computing device, a screenshot of the live broadcasting data stream in response to the server's determining that the network state of the computing terminal is the mobile data network. ### Claim 8 (depends on 7) The method according to claim 7, further comprising: receiving, by the computing device, a blurred screenshot obtained by a blur processing performed on the screenshot. ### Claim 9 (depends on 7) The according to claim 7, further comprising: receiving, by the computing device, a low-fidelity live data stream converted from the live broadcasting data stream. ### Claim 10 (depends on 7) The according to claim 7, further comprising: prior to receiving the live broadcasting data stream or the screenshot of the live broadcasting data stream, presenting a message container on the group session interface, the message container covering a first area of the group session interface;
