Legend has it that the souls of the deceased will rush to a river named Wangchuan; there is a bridge over the Wangchuan named Naihe. If you want to cross the River of Forgetfulness, you must pass through Naihe; if you want to pass through Naihe, you must first abandon everything in the world. "Where am I?" "Underworld." "Underworld... Underworld?! Am I dead?" "Yes."
