 众所周知，TCP 是面向字节流的传输层协议，其数据传输没有明确的边界，因此应用层读取的数据可能包含多个请求而导致无法处理业务。  
 
-[msgpack](https://pkg.go.dev/github.com/lim-yoona/msgpack) 就是为了解决这个问题，将请求数据封装成消息，发送时打包，接收时解包。

-## What dose msgpack do?  
+## What dose tcpack do?  
 
 As we all know, TCP is a transport layer protocol oriented to byte streams. Its data transmission has no clear boundaries, so the data read by the application layer may contain multiple requests and cannot be processed.   
 
-[msgpack](https://pkg.go.dev/github.com/lim-yoona/msgpack) is to solve this problem by encapsulating the request data into a message, packaging it when sending and unpacking it when receiving.
