What do you mean when you say that Tang Yao Minister Hao Tao rules the prison, supplemented by a one-horned sheep?

Ni introduced that today, he is a national judge. He has a sheep called "Pleasant Goat", which is a one-horned sheep, so-called "Goat's Horn". This one-horned sheep has divinity and can tell who is guilty. Hao Tao, as he is unable to hear the case at present, will ask him to help solve the case.

"In fact, this kind of' claw' that hates evil is also called' the West' and' the beast of law'." Ni said that during the Warring States period, imperial censors, prison officials and other law enforcers in Qin Chu and other countries all wore crowns with the pattern of the one-horned god sheep to show solemnity, justice and sacredness. At the same time, a kind of horn hat was invented, which judges must wear when trying cases, to show that they are observant and impartial in handling cases. Therefore, this kind of hat is called "arrogant crown", also known as "law crown".
