The Buddha said: Flowers bloom for a thousand years, fall for a thousand years, flowers and leaves never meet, love is not cause and effect, fate is destined to life and death. One road, called Yellow Spring, is full of sorrows; A river, named Lethe River, overflows and is desolate; A Naha, carrying Lethe; A bowl of Meng Po soup can forget this life in exchange for the next life; A stone, standing on the bank of the Lethe River, is called Sansheng; A well, indicating the afterlife, a familiar figure, happily jumped down; A face, in the next life, will be a ...... for you. The other side of the flower, the tenderness of the devil. The red flowers bloom in hell and the white flowers bloom in heaven. Legend has it that a long, long time ago, on the banks of the Santu River in the underworld, a large number of flowers bloomed on the other side, far like a carpet paved with blood, red like fire, like a river, and was called "the road of fire". This is also the only scenery and color on this long yellow spring road, and people follow the guidance of this flower to the hell of the netherworld.
