According to The Journey to the West's records, King Jinjiao and King Yinjiao of Pingdingshan all called Kyubi no Youko fox who pressed Longshan to press Longdong as his mother, probably the dopted mother who was recognized after the Second Demon, because Jinjiao and Yinjiao were the lower bounds of the old gentleman boy guarding the gossip furnace, and the old gentleman boy could not have the mother of a fox, but only the dopted mother who was recognized after the Second Demon. As for who Jinjiao and Yinjiao's mother are, the original work did not explain.

In the thirty-fourth journey to the west, the demon king cleverly deceived the trapped ape sage and cheated the baby away.

-The Second Demon (Yinjiao) said, "I still have a seven-star sword and a banana fan beside me. That golden rope was left by my old mother in Yalong Mountain and Yalong Cave. Now I've sent two little devils to treat my mother to the Tang monk's meat and ask her to bring a golden rope to fetch Monkey. " ..... When the old monster heard people humming and leaned out of the sedan chair to look at it, Monkey jumped in front, punched a hole with a stick, and his brains popped out, dragging out the sedan chair to look at it. It turned out to be a Kyubi no Youko fox.
