General regulations

There is a shepherd herding sheep in the valley. He is always on his guard when he sees a wolf following him in the distance. Months passed, and the wolf just followed from afar, not near the sheep, let alone hurting a sheep. The shepherd gradually relaxed his vigilance against wolves. Later, the shepherd thought it was good for the wolf to follow the sheep, so he didn't have to be wary of other wild animals. Later, he simply regarded the wolf as a sheepdog and told it to look after the sheep. When the shepherd saw that the wolf managed the sheep well, he thought: People say that the wolf is the worst, but I don't think so ... One day, the shepherd had something to go to town, so he entrusted the sheep to the wolf, and the wolf agreed. The wolf estimated that the shepherd had entered the city and howled loudly in the forest. Its howling attracted many wolves, big and small. All the sheep were eaten by wolves.

The shepherd didn't understand the nature of the wolf, so he was deceived by the wolf's hypocrisy. The idiom "inviting the wolf into the house" means bringing the bad guys into the house.
