What does burning paper during a funeral mean to relieve the disaster?

That is, after the sedan chair burned for ghosts is burned to ashes, it is freed from the shackles of this space in another space (or the underworld). The ghosts or souls get on the sedan chair and leave without being talked to. They are afraid of talking to you later.

After all, yin and yang are separated at home. In fact, it is just people's good wishes. People who do many bad things will not be able to sit on them when they are burned. When people who do many good things die, there will be yin and yang, or the heavenly beings will carry the sedan to pick them up.
