When erecting a monument to the tomb of the deceased, it is necessary to correspond to the date of birth and the owner of the tomb, and choose the time for erecting the monument according to the date of birth, the deceased and the owner of the tomb. It is forbidden to compete with birthdays, the dead and the living, otherwise it is taboo. Only by choosing the right time to erect a monument and attaching importance to the geomantic omen of the cemetery can future generations prosper.
