Xiezhi
The xiezhi was said to be a single horned ram, with black fur and burning eyes. Although in artistic depictions it more often looks like a cross between a qilin and a lion, always with a single horn or antler. The xiezhi is an ideally just beast and can intrinsically distinguish between the just and unjust people in the world. It is a highly intelligent beast and can understand all human languages. The xiezhi will hunt down evil doers and stab them with its single horn and devour them. It was believed that the legendary emperor Shun had a captive xiezhi, who would preside over court hearings and ram the guilty party. The censorate of the Ming and Qing periods wore xiezhi badges as a sign of their office. Among common people the image of the xiezhi was believed to ward off evil and protect them from crime. Similar creatures could be found in other parts of Asia. In Japan it was known as the sinyou and in Korea it was known as the haetae.
