I don’t know how to refuse someone else’s request to change positions.

First, you are not obliged to change places with others.

Second, if you violate your inner thoughts, you will hate yourself very much!

You can say, I like my current position and don’t want to change it yet! You can discuss it with others! (Remember, don’t look sorry for others when you refuse. Others will press on you when they see your weakness. You must know how to defend your rights!)
