The origin of the oil pan under the knife

Buddhism has the so-called "Ten Realms", that is, there are ten realms in the world, namely, Buddha, Bodhisattva, Jue Yuan, Wensheng, Heaven, Man, Asura, beast, evil spirits and hell. The first four are called "four saints", that is, they transcend the sacred world and get rid of the suffering of life and death. The last six kinds are called "six mysteries", which need endless circulation in filthy soil. The last three kinds are also called "three evils" and "three evils", which is a more unfortunate realm, and hell is the most unfortunate. Speaking of hell, it is chilling, with as many as eighteen floors. The further you go, the deeper the pain. In hell, there are not only demons such as Yamaraja, judges and ghosts, but also all kinds of torture such as knife mountain, oil pan, disc mill, saw and stone mill. Therefore, people are most afraid of entering eighteen layers of hell after death.
