从root用户转到user用户查看f.txt文本文件时提示没有权限
[root@localhost ~]# ll /home/struggleh_27/f.txt
-rw-rwxrw-+ 1 root root 22 4月 11 14:53 /home/struggleh_27/f.txt
[root@localhost ~]# getfacl /home/struggleh_27/f.txt
getfacl: Removing leading '/' from absolute path names
file: home/struggleh_27/f.txt
owner: root
group: root
user::rw-
user:user:rwx
group::r--
mask::rwx
other::rw-
[root@localhost ~]# su user
[user@localhost root]$ cat /home/struggleh_27/f.txt
cat: /home/struggleh_27/f.txt: 权限不够
请问为什么这样啊，怎么才能使用user用户查看
