Black snakes spit letters, crows are in the air, and black pigs cross the river at the same time in one place (those who know Feng Shui come in for answers! )

If these three symptoms appear in one place at the same time, it can be proved that the yin in this place is not unusually heavy! If you want to go here, don't stand on the letter of the black snake! If you insist on going, please go to a nearby temple and grab a handful of incense ashes and a bag of glutinous rice to ward off evil spirits! Also, don't go alone, be sure to go together! If you see trees dying and a dry river on the road, and the river bed is still deep and there are dark clouds in the sky, please be sure to go back the same way! ! ! Because, this is exactly' black snakes spit letters, crows are in the sky, and black pigs cross the river'! ! ! (If you see a vaguely protruding trace on the bottom of the river, there may be a person in it ... If this person is unwilling before he dies, he will become a spectre. )
