    login_frame.destroy()
    root.title('与%s聊天中' % chat_to)

# 运行主程序
root.mainloop()

主要修改如下：
1. 定义了字典dic，将表情标识符与表情图片一一对应。
2. 修改了send_mark函数，将表情图片对应的标识符放在消息中一起发送。
3. 修改了bb1、bb2、bb3、bb4、bb5函数，调用send_mark函数发送表情。
4. 修改了express_board函数，打开表情面板时，创建表情图片对应的按钮，并将其放置在窗口上；关闭表情面板时，销毁这些按钮。
5. 修改了receive_message函数，处理接收到的消息中包含表情标识符的情况，在消息框中创建表情图片。
