How can I see the news that someone has withdrawn from the competition?

How can I see the news that QQ has been withdrawn by others? You can't see it unless he sends it, but you can't see it unless he withdraws the news, so you can't see it. No one can tell. Withdrawing this message means that if he doesn't send it, it will be deleted automatically. No one can see it, so you can't see it unless he doesn't withdraw the message. That's what happens in the game.
