Why does the old man die with his mouth open?

Regarding death, everyone has always been quite taboo. But in Chinese tradition, even if many people leave, there must be an image of him leaving. Change into clean clothes and pants, even if it is a funeral, you have to do it with all your heart. However, many relatives will find an embarrassing problem when sorting out the deceased's affairs: after the person leaves, they keep their mouth open for some reason.

There are many names for this phenomenon in folk customs. Some people stretch their legs because they feel dry mouth before leaving, while others stretch their legs involuntarily because they have difficulty breathing before stopping the heartbeat. But in fact, these names are all wrong. There is no scientific evidence. They are just people's speculation and self-comfort for those who have passed away.

In fact, this matter has certain basis and expression in scientific research. Human death is not an instantaneous thing. Every organ in the human body will stop working after a certain period of time, until the brain dies and then leaves completely. At this time, the muscles of the body are very stiff and almost defenseless.

Since the muscles have lost their charm, even the muscles of the face are bulging out, which is affected by gravity. Therefore, the mandible will naturally relax, which can easily cause others to misunderstand that it is opening its mouth, but in fact it is not the case at all.

When the human brain dies, all functions of the human body are naturally lost, so some folk names are not valid at all. However, in order to protect the deceased, in many places, when encountering such things, relatives will put some paper or something like that in their mouths, so that even if there is really another world, it will be very vivid. In ancient times, what was in the mouth represented one’s true identity.

People attach great importance to appearance when they are alive, and of course they have to be decent after they die. Although many traditions of the older generation have no scientific evidence, they have been like this for many years and should be given a certain amount of attention, at least to ensure that they are not slandered.
