Htaccess redirection any folder with variables

I am trying to do redirection with htaccess.

My code is

RewriteRule ^cn/folder1/folder2/(.*)$ /cn/folder2/$1 [R=301,L,N]

I am trying to redirect if any request comes like;

cn/folder1/folder2/bar

redirect it to

cn/folder2/bar

folder1 and folder2 can be change.

So,

cn/folder5/folder6/bar

needs to redirect to

cn/folder6/bar

Can I do with a single line code? I tried to do it but cannot find anything.
