 # 一些易混淆的点
 1. 客户端创建的套接字包含指定`目标的IP地址和端口号`（TcpClientImpl类中的init函数），服务器创建的套接字只包含`本机IP地址和监听端口`。
 
-2. 在网络编程中，服务器通常会在一个监听端口上等待来自客户端的连接请求。当服务器接受到一个连接请求时，它会创建一个新的套接字（或文件描述符）来表示这个新建立的连接，并且通常会为这个新的连接设置一系列的事件回调函数。
+2. 在网络编程中，`服务器`通常会在一个监听端口上等待来自客户端的连接请求。当服务器接受到一个连接请求时，它会创建一个新的套接字（或文件描述符）来表示这个新建立的连接（TcpClientAccept类实例），并且通常会为这个新的连接设置一系列的事件回调函数。
 
 3. 客户端实例（TcpClientImpl类对象）进行init操作时，会创建一个套接字并对目标服务器发出连接请求并启动事件循环（Loop函数），然后客户端实例会一直进行事件循环（监听是否有读写操作）直至连接关闭（Close函数）。

 # 该模块的实现过程
 ## 服务器端：
 1. 创建服务器端套接字：使用 hloop_create_tcp_server 函数创建一个新的 TCP 服务器端套接字，并指定要监听的 IP 地址和端口号。
