Wandering ghosts, unclean ghosts Souls that have people to make offerings to them may rest in peace, and won't be troublesome. Thus only one type of specter makes itself visible to man: the "lonely soul" or "wandering ghost" that either has no one to look after it or has died a violent death.
有人供養祭拜的鬼，安心地歸於極樂世界，不會四處作怪；所以讓人看見的鬼，其實只有一種：就是沒人祭祀或凶死的「孤魂野鬼」。
