Wang Hu lived under [Liu] Song rule (420-79 CE), and was from Chang’an. His paternal uncle had been dead some years when, in the twenty-third year of the Yuanjia era (446 CE), he suddenly reappeared and returned to the family home. He demanded Hu improve his conduct, in which there were defects, family affairs having been neglected. He punished Hu with five strokes of the cane. Passersby people in the neighbourhood heard both their conversation and the noise of the beating. They could also see the welts left by the cane, but could not see the manifestation, which appeared only to Hu himself. His uncle told Hu: “I did not deserve death. The tomb passage waits for my number to appear on the register of spirits. Today there will be a great gathering of officials and troops, and I fear that the village may come to harm, so I do not set out.” Hu could also make out a crowd of spirits in noise and disorder beyond the village boundary.
Presently his uncle said goodbye and departed, telling him: “I will come on the seventh day of the seventh month. This will be short visit, and I wish to take you along the roads of the nether world, to make you understand the consequences of virtue and of evil. There is no need to be extravagant in laying out offerings; tea and cakes will suffice.”
When the day came, he did indeed return. He told Hu’s family: “I’m now taking Hu to see the sights. When the trip is complete he will return. There is no reason for alarm.” Hu then felt tired and laid on his bed, then became quite still, as if he were quite dead. His uncle then took Hu deep into the mountain ranges, where they observed the various spirits and demons. Finally, they reached the highest peaks, and the various spirits spoke to Hu, and also laid out food. The produce and flavours were not so different from those in the world of the living, but the ginger was especially fresh and delicious. Hu yearned for this, and was about to return when those around him laughed and told him: “You should stay and eat this. You won’t get far anyway.”
Hu saw a further place, a vast and beautiful building, with gorgeous canopies and elegant bamboo mats. There were  two young monks living in it, and when Hu arrived they laid out a great spread of fruit, betel nuts and other produce. Hu spent a long time travelling, and saw all the conequences of virtue and vice, both sweet and bitter. He then said his farewells to return, and his uncle told him: “You now understand the need to cultivate virtue. When you return home seek the white-foot āranya temple; these people are ascetics of the highest order, and you should afford them respect as your teachers.” These priests of Chang’an had white feet, and so were known to people at that time as the white-foot āranya. They were shown great respect by Wei Lu, with Prince Lu revering them as his teachers.
Hu followed these instructions, travelling to study at Gaoshan with a young monk. Amid the crowds, however, he suddenly caught sight of those two monks. Hu was greatly shocked, and went to speak to them, asking when they had arrived. The two monks replied: “We poor clerics belong to this very temple. We are not aware of any prior acquaintance with the gentleman.” Hu again described their meeting in the high mountains, but the assembled monks told him: “The gentleman is simply mistaken. How could that have taken place?” When the next day dawned, however, the two monks had departed without saying farewell. Hu thus informed the gathered Buddhist monks about the whole matter, and his meeting with the two monks on Gaoshan. The crowd were all astonished, and sent people to seek the pair of monks, but their location remains unknown.

宋王胡者。長安人也。叔死數載。元嘉二十三年。忽形見還家。責胡以修謹有缺。家事不理。罰胡五杖。傍人及鄰里。並聞其語及杖聲。又見杖瘢。而不見其形。唯胡獨得親接。叔謂胡曰。吾不應死。神道須吾筭諸鬼錄。今大從吏兵。恐驚損鄉里。故不將進耳。胡亦大見衆鬼紛鬧于村外。俄而辭去曰。吾來年七月七日。當復暫還。欲將汝行。遊歷幽途。使知罪福之報也。不須費設。若意不已。止可茶食耳。至期果還。語胡家人云。吾今將胡遊觀。觀畢當還。不足憂也。胡即頓臥牀上。泯然如盡。叔於是將胡遍觀群山。備觀鬼怪。末至嵩高山。諸鬼道胡。並有饌設。其品味不異世中。唯姜甚脆美。胡懷之將還。左右人笑云。止可此食。不得將遠也。胡又見一處。屋宇華曠。帳筵精美。有  二少僧居焉。胡造之。二僧為設雜果梹榔等。胡遊歷久之。備見罪福苦樂之報。及辭歸。叔謂曰。汝即已知善之當修。返家尋白足阿練。此人戒行精高。可師事也。長安道人足白。故時人謂為白足阿練也。甚為魏虜所敬。虜王事為師。胡即奉此訓。遂與嵩山上年少僧者遊學。衆中忽見二僧。胡大驚。與敘乖闊。問何時來此。二僧云。貧道本住此寺。往日不意與君相識。胡復說嵩高之遇。衆僧云。君謬耳。豈有此耶。至明日。二僧不辭而去。胡乃具告諸沙門。敘說往日嵩山所見。衆咸驚怪。即追求二僧。不知所在。
