If one day we face death, what kind of funeral do you want to give yourself?

I hope that when I leave this world, I can donate my useful organs to patients in need in the Third Hospital of Beijing Medical University, and the rest to Peking University Medical Center for experimental research or anatomical experiments for students. I don't want an open funeral, but I want to care about my family and friends, say goodbye to me in a way that they prefer/accept more easily, and then move on. ?
