Yang Ke once heard of a place where the sacrificial customs were very barbaric and bloody. In order for the ancestors to have something to eat and someone to serve them, outsiders who entered by mistake or were tricked would be tied to a beach and beheaded as human sacrifices, leaving their heads to bleed. At that time, the entire beach was bloody, and even crazy people would go on a killing spree in other places and cut off the heads. The man warned that if you enter by mistake, don't go to the roadside, and don't eat or drink the food and water provided by the locals, because the people going to worship can tell whether you are a local, and if you are not, they will take you away.
