Of course, in ancient times, a coffin usually contained more than just one jade artifact. The so-called 'Jade Seals the Nine Orifices', as the name implies, means using jade to seal nine parts of the body.
The nine orifices refer to a person's two eyes, two nostrils, mouth, two ears, as well as the genitals and anus.
The ancients had an almost superstitious reverence towards jade, firmly believing that jade could ensure the peace of the living and the immortality of the dead. So during burial, they would use jade artifacts to seal the nine orifices of the corpse, believing that doing so would ensure the body never decays.
This theory is obviously without logic or scientific basis, but starting from the Han Dynasty, this practice became extremely popular. Besides jade clothing, nine orifices jade also became an essential set of items for the wealthy to use in burials.
