Silk is a kind of white silk fabric, on which characters, animals, birds, gods and animals are depicted with pen, ink and color. It rose in the Warring States and reached its peak in the Western Han Dynasty.
The ancients believed that after death, the soul attached to the human body should be separated from the body. People become wild ghosts after being separated, so they can't enjoy the sacrifices of future generations, and they will also disturb future generations. So we must find a way to get the scattered souls back and bury them. The burial system is called evocation. Evocation is to make an evocation banner, so that the wandering souls outside can identify the banner with the image of the tomb owner and return by themselves. Restoring the spirit is to leave the coffin at home for a few days before the funeral, and the spirit can also be possessed. The general practice is that the coffin is parked in the mourning hall, and there is a painted evocation coffin in front of the coffin, which the ancients called Ming Jing. At the funeral, hold it in front of the coffin, guide it all the way to the burial place, and put it on the coffin after the farewell ceremony. If there are more than one coffin, put it on the innermost coffin and bury it, so that the soul will follow the coffin and go to the grave together. T-shaped silk painting is a complication of evocation. Evocation can ascend to heaven, and the spirit can enter the ground to seek peace, which is the wish of future generations.
