+- The client is divided into two roles:
   - Leader: Be responsible for maintaining the connection with the remote server, only one Leader for the same type of client.
   - Follower: Delegate specific operations to the Leader. A common way is Subscribe-Model (let the Leader interact with remote server and wait for its return).
 - How to determine who Leader is, who Follower is? There are two modes:

 - 客户端会被区分为两种角色：
   - Leader: 负责和远程服务端维持连接，对于同一类的客户端只有一个 Leader。
   - Follower: 会将具体的操作委托给 Leader，常见的是订阅模型（让 Leader 和远程服务端交互，并等待其返回）。
