I am a teacher and I have to admit that one of our students has changed the title of 1.2 in the one child policy page. I have changed it to administrator.
We are very sorry for any extra work that this has created. He is being dealt with by our deputy headmaster as we speak. Please feel free to contact me for further details.

Maybe this is about en.wikipedia.org ? If so that seems to have been reverted in https://en.wikipedia.org/w/index.php?title=One-child_policy&type=revision&diff=684898468&oldid=684898154
Since this is the only post with your user account, I believe that you may have posted this in the wrong place.
Generally, protecting a page prevents unprivileged users from editing it. Note that there also is an option for a cascading protection: If the cascadingly protected page includes templates, then these templates automatically get protected as well.
