Which fortune teller said that his family was unhappy because of Guanyin statue?

Because it is not turned on, or for other special reasons. Some supernatural animals, such as weasels, snakes and foxes, may be attached to the Guanyin statue, and then these "immortals" will play tricks on his family.

It's okay to worship Taoist immortals, because immortals dare not attach themselves to them, for fear that patrolling immortals will be punished if they find out. Buddhists are merciful, generally regardless of these. The name "Xianjia" is actually the spirit of animals, so the spirit of animals likes to attach to Buddha statues.

Let him send the Buddha away to the temple, and then let the real monk open it later.
