In ancient times, most human beings, including emperors, aspired to immortality and feared death, which is understandable, like the most famous one, Qin Shi Huang, who had been sending out medical practitioners around to seek medicine and wanted to live forever, that is, during the Wei and Jin dynasties, the concept of reincarnation of life and death was deeply engraved in everyone's heart. Facing death is not scary, what is scary is that you have done so much evil while you were alive that when you die you will go to hell and will be judged by Hades, who will give you more punishment, and Hades is also shown in this series of my work.Conversely, the fresh ideas brought by Buddhist culture have given ghost culture a new dimension of creativity. It adds to the idea of cosmic space and the idea of life and time to ghost stories.The ghost novels of the Wei and Jin dynasties were greatly enhanced by the nourishment of Buddhism and reached their peak level until the Tang dynasty. Since ancient times ghost cultures have wanted to set up independent religions, developing like Satanism in the United States, but after Buddhism entered China, instead of setting up independent religions, ghost cultures even became a cultural buffer zone between Buddhism and Taoism, helping to unite Buddhism, Taoism and Confucianism and becoming more culturally adapted to the general context of China at the time. During the same period, because of the Buddhist theory of the cycle of good and evil, karma and retribution, the ghost culture added a punitive function, and many people would feel fear inside after doing something bad, for example, after killing someone they would fear that the deceased would turn into a ghost to seek revenge on them. There is a Chinese proverb that says, "If you don't do anything wrong, you won't be afraid of ghosts knocking at your door. This is also how it comes about. So on another level, ordinary people who do bad things have a cost and will have a psychological burden. It is also from this period that people will have the concept of punishing evil and promoting good. In contrast to the Buddhist concept, the traditional Chinese concept of good and evil mainly emphasises moral self-restraint and has little deterrent effect on punishment, and mostly uses ghostly vengeance or celestial induction to imply the concept of good and evil. In contrast, the Buddhist concept of hell holds that every soul is equal in hell and will be judged, and that all karma is recorded in a book of ghosts, which will be judged and punished according to karma, and sent to different hells according to different sins. Buddhism emphasises that "the net of heaven is wide open", that no good can come to the wicked, and that punishment is shockingly cruel. The Buddhist concepts of hellish judgement, karma and the six paths of reincarnation are interlinked and have had a strong psychological influence on the traditional Chinese view of good and evil, and even on ghost culture and the underworld, leading to a large number of ghost stories with stories of hellish judgement and punishment. This influence has even come to the point that now, when most of society believes in science, the police will still use the fear of criminals after they have committed a crime to arrest them, and will even create psychic phenomena to break through the psychological defences of the prisoners.  The ghosts, wiser than the saints, watch over human behaviour in the underworld and are ready to punish. In this sense, the ghost story, like law and morality, maintains the fairness and justice of society. Its punitive function for society, subjectively, plays the role of self-restraint, with good people and the promotion of virtue, and objectively contributes to social indoctrination, maintaining social ethics and morality and regulating social behaviour. It helps Buddhism to teach the people from the side. Even more incredible to me was that Venerable Chuan Yi told me that ghosts can also become Buddhas, which was the source of my second unit theme. The Venerable told me that the Buddha was willing to redeem all sentient beings, including ghosts and monsters. The Bodhisattva of the Earth often goes to hell to redeem ghosts and monsters. Buddhism teaches the Six realms wheel of life, which includes Naturelaw, Asura Road, humanity, beasts Road, hungry Road, Hell Road, and that all things can become Buddha because all things have Buddha nature. The equality of all beings is at the heart of what is important.
