说明：  使用QT平台和网络编程写的一个聊天室，可视化界面没有任何美化的最初版本，功能可以实现群聊以及私聊，因为是比较简单初版，所以可以继续优化和添加功能，比如修改发送和接收的数据类型，使聊天室不仅仅可以聊天，还可以发送文件等等。
(In a chat room written by using the QT platform and network programming, the visual interface has no beautified initial version. The functions can realize group chat and private chat. Because it is a relatively simple initial version, it can continue to optimize and add functions, such as modifying the data types sent and received, so that the chat room can not only chat, but also send files and so on.)
