Diyu, often referred to as "Hell" in Chinese mythology, is a complex underworld where souls are judged after death. It is depicted as a multi-layered realm, consisting of various courts and levels, each designed for different types of punishment based on one's actions during life. The concept emphasizes moral accountability and the belief in karma. In Diyu, souls undergo trials and face consequences for their deeds, which can include physical torment or psychological suffering. The ultimate goal is to purify the soul, allowing it to be reincarnated into a better life. This belief reflects the importance of ethics and morality in Chinese culture.
