In the Cantonese Taoist Dazhai customary rituals, there are also shift-in rituals for the deceased to enter into their house in the netherworld. Believers believe that the Yin and Yang worlds are synchronized. The relocation to a new house in the living world requires a shfit-in ceremony to allow home owners to have a blessed home to bring good luck and prosperity to the home and family. And the same apply to the deceased in the netherworld.
Usually, this kind of ritual is only seen in the Dazhai ritual during the three-seventh, seven-seventh, or hundred-day. There are also differences in the offerings and prayer chanting in both the Yin and Yang ‘shifting-in ceremony’.
