What did my uncle say to him before he died?

No one wants to die, so for a person who is about to leave the personnel, survival is his instinct, so you can only say to your uncle: it's okay, you will be fine, and my aunt and I are waiting for you to recover. After that, there is no need to do other excessive comfort, because for a dying person, his heart knows the result, but he can't change the predicament, so his heart is full of helplessness. No matter how much you say to people who are full of helplessness, you are powerless.
