“San-Tu” in Taoism means three special places. These are the most horrifying places in the universe. They are the place in hell where the blaze of death burns, the place in hell where the animals cannibalize each others, and the place in hell where hungry ghosts facing the swords and slaughtering.
“Wu-Ku” means five types of misery. They are the misery of falling into hell blades, the misery of falling into hell sword trees, the misery of falling into hell burning copper pillars, the misery of falling into hell boiling liquid, the misery of falling into hell of oceans filled with man-eating beasts.
