There is a blue brick under the old house that says is Sakyamuni Buddha a town house?

It should belong to the town house, but wherever there is a Buddha's name, there are Buddha and Bodhisattva blessings to avoid misfortune. Just like placing a tablet of Amitabha in a place where children often drown will reduce the drowning mortality (we have tried to verify it many times by launching a circle of Buddhist friends), but this practice is different from the routine of Buddhism. If you don't do it well, it will affect your respect and piety for Buddha and Bodhisattva. We Buddhist disciples generally do not advocate it, but it is better to worship the Buddha.
