In the autumn the pilgrims found themselves in the Ssu Ha Li Country, where everything was red--red walls, red tiles, red varnish on doors and furniture. Sixty _li_ from this place was the Flaming Mountain, which lay on their road westward.
An old man they met told them that it was possible to cross the Flaming Mountain only if they had the Magic Iron Fan, which, waved once, quenched fire, waved a second time produced strong wind, and waved a third time produced rain. This magic fan was kept by the Iron-fan Princess in a cave on Ts'ui-yün Shan, 1500 _li_ distant. On hearing this, Sun mounted a cloud, and in an instant was transported to the cave. The Iron-fan Princess was one of the _lochas_ (wives and daughters of demons), and the mother of the Red Child Demon, who had become a disciple of Kuan Yin. On seeing Sun she was very angry, and determined to be revenged for the outwitting of her husband, King Ox-head, and for the carrying away of her son. The Monkey said: "If you lend me the Iron Fan I will bring your son to see you." For answer she struck him with a sword. They then fell to fighting, the contest lasting a long while, until at length, feeling her strength failing, the Princess took out the Iron Fan and waved it. The wind it raised blew Sun to a distance of 84,000 _li_, and whirled him about like a leaf in a whirlwind. But he soon returned, reinforced by further magic power lent him by the Buddhist saints. The Princess, however, deceived him by giving him a fan which increased the flames of the mountain instead of quenching them. Sun and his friends had to retreat more than 20 _li_, or they would have been burned.
The local mountain-gods now appeared, bringing refreshments, and urging the pilgrims to get the Fan so as to enable them to proceed on their journey. Sun pointed to his fan and said: "Is not this the Fan?" They smiled and said: "No, this is a false one which the Princess has given you." They added: "Originally there was no Flaming Mountain, but when you upset the furnace in Heaven five hundred years ago the fire fell here, and has been burning ever since. For not having taken more care in Heaven, we have been set to guard it. The Demon-king Ox-head, though he married the _locha_ Princess, deserted her some two years ago for the only daughter of a fox-king. They live at Chi-lei Shan, some three thousand _li_ from here. If you can get the true Iron Fan through his help you will be able to extinguish the flames, take your Master to the West, save the lives of many people round here, and enable us to return to Heaven once more."
