How to write a note when someone else's position is occupied?

When my parking space is occupied by someone else's car, from the perspective of rationality and harmony, I will give a warm reminder with a note. The note should first indicate that the ownership or use right of this parking space belongs to me, then tell the parties not to occupy other people's parking spaces at will, third, tell you where to park, fourth, tell you the consequences of occupying other people's parking spaces, and finally ask him for understanding.
