I think the trading market is the six paths of reincarnation, distinguishing between good and evil, and human nature's greed, anger, stupidity, pride, and suspicion.
We are all practitioners:
The Way of Heaven: Symbolizes "enjoying the realm of happiness and joy".
Humanity: represents the process of human beings living, working, practicing in the world, and experiencing various joys, sorrows, and joys.
Asura said: Corresponding to the Shura world, it symbolizes the existence of half gods and half ghosts, with the nature of desire and struggle.
Animal Path: Represents the animal kingdom, where all living beings experience various pains and sufferings and are restricted by the cycle of life and death.
Hungry Ghost Realm: Corresponds to the Hungry Ghost Realm, where all living beings are tortured by hunger, desire, and suffer due to greed.
Hell: Represents the hell realm, where all living beings are punished by the consequences of their sins and experience endless pain and torture.
