"The Empty Stone Sutra" records: There are spirits in heaven and earth, and their names are gods. Gods are born with great power, and their nature is gentle and kind. There are two sons: they are called demons and ghosts. Demons are inherently vicious and vicious, while ghosts are cruel and bloodthirsty. God realized that time was running out and sealed the demons and ghosts separately. The demons and ghosts fought back, but God finally sealed them. This is the day God died, and it is known in history as the day God died.
