It's a bit cumbersome using absolute paths when you only want to jump from one branch of the tree to another nearby. That's why CD allows you to use relative paths.

当您只想从目录树的一个分支跳转到附近的另一个分支时，使用绝对路径会有点麻烦，这就是cd命令允许使用相对路径的原因。

An absolute pathname begins with the root directory and follows the tree branch by branch until the path to the desired directory or file is completed.

绝对路径名从根目录开始，通过一个又一个的分支，一直到你要去的目录或者文件为止。
