Shen Luo recalled for a moment and then suddenly remembered that back in the Western Regions, Little Monk Jiang Liu had talked about how the Ksitigarbha Bodhisattva had made the great vow, "Not until the hells are empty will I become a Buddha," and afterwards took up residence in the Underworld, to redeem the ten thousand ghosts there.
At that time, he had mentioned that the Underworld has ferry points for guiding lost souls scattered across the Four Great Continents, and those established within major State Cities are namely the City God Temples.
Those distributed in remote mountains are called "Ghost Mountain Gates," under the jurisdiction of some minor mountain gods, while those located in the Rivers and water areas are under the control of the Water Deity and are called "Yellow River Crossings."
