A sign that the old man sleeps by the pillow.

This is a sign that the old man will die. Generally speaking, if there are several people lying on the bed, just put a few pillows to avoid putting more pillows, which is also easy to attract ghosts to bed. It is the same for old people to sleep only by pillows, because the other side may be occupied by ghosts, so old people sleep only by pillows. Note: The answers are for reference only.
