Abstract: Embodiments of the present application provide a method and system for private chat within a group chat. During operation, the system receives, at a server from a computing device, a first message that includes a first private chat identifier, private chat counterpart information, and private chat content data. The system determines a private chat counterpart client based on the first private chat identifier and the private chat counterpart information. The private chat counterpart client and the computing device are both participating in the group chat. The system generates a private chat message based on the first message including the private chat content data, and sends the private chat message to the private chat counterpart client without sending the private chat message to all members participating in the group chat.
