I am a security guard recruited by the property management company. Because I played with my mobile phone at work and put my feet on my work, I was transferred out by the property leaders.

The question is unclear, should I transfer from my unit or expel you?

Playing mobile phone at work is dereliction of duty, and any punishment is reasonable. Or you can look at how the labor contract signed with you at that time was stipulated.

I wish I hadn't written these things in the document. You can write a resignation report and ask not to fire you. This will not be recorded in the file.
