Thus, ancestral ghosts find they have no choice but to appear when they are disturbed or in trouble--when their graves have been flooded, when their corpses have been impaled by the roots of a tree, when no one has come to make offerings for a long time and they haven't a cent to their name.
碰到這樣墳墓淹水，屍體遭樹根穿過，或是子孫久未祭拜，使得祖先鬼缺少銀兩度日等，「靈魂受擾與不安」的困境時，祖先也不得不現身了。
