How long can't the old man get a haircut after he dies?

China traditionally doesn't have a haircut for three months, and customs vary from place to place. There are different opinions on the specific reasons. For example, in order to express the memory of the deceased, it is said that the hair is full of human soul, but also contains the blood of the same blood. When your family just died, your hair was cut, and the soul of the deceased can easily take away your soul. There are too many arguments.
