Problem background, ordinary users access files of other user groups, but cannot access normally, so there is the following solution
The first solution found
How to add an item "Open current folder with root privileges" in thunar - Ubuntu Chinese Forum
In the thunar explorer, select the menu Edit - "configure custom action "command" and write gksudo thunar %f

I continued to read and finally found
Thunar right-click menu and other customization - dylanchu - Blog Park (cnblogs.com)

Enter
cd /usr/share/polkit-1/actions
backup
sudo mv org.xfce.thunar.policy org.xfce.thunar.policy.back

Change the relevant default values to the following
<defaults>
<allow_any>auth_admin</allow_any>
<allow_inactive>auth_admin</allow_inactive>
<allow_active>auth_admin</allow_active>
</defaults>
Final Results
