Why do people have to die for three days after death?

Keeping in the body for about three days is to avoid suspended animation.

After entering a state of shock, people's physical functions will gradually disappear, with no breathing, no heartbeat and no vital signs. But three days later, the body resumed its life characteristics. In ancient times, there were many cases of suspended animation. For example, Bian Que thought the prince's death was a little strange. After giving him an injection, the prince sat up successfully, and there was nothing wrong with normal people. In order to determine whether this person is really dead, it needs to stop for three days, but in a way, stopping for three days is also the basis for determining death.

The origin of the custom of staying dead actually originated in ancient times, and ancient people have always had such a custom. During the Spring and Autumn Period, the custom of mortuary was formed.
