What do you think of occupying space for others?
If you want to fight for your own interests, you can do something euphemistic: for example, you can say with a smile that I am a little uncomfortable sitting here and get up when they come; It doesn't matter if you don't come. When you come, ask the people who come if they want to sit in the room. It doesn't matter if you don't sit. If you still want to sit, let your seat be regarded as "respecting the old and loving the young"-you can make a toast in your heart!
