This is a story from <Journey to the west>.Red Boy, the Bull Demon King and Princess Iron Fans son, had cultivated his physical and mental capacities and pollessed magic abilities. With powerful magics he always had the idea of eating the meat of Sanzang,the Tang Priest (whose meat could make creatures live longer) to lengthen his life.

One day while he was watching in the sky, he saw Sanzang and his disciples coming from afar. He knew that the disciples had excellent fighting skills, so he planned to capture Sanzang by making use of the priest's kindness and muddled mind, rather than use force.

At a spot just ahead of where Sanzang and his group were, Red Boy turned himself into a boy of seven and hung himself on the top of a tree with his hands and feet tied with a rope and cried for help. The Tang Priest heard the boy's cries and asked Monkey to release him. Monkey, seeing that the boy was actually a demon in disguise, told his master not to bother. Sanzang got angry, and he asked Pig to bring the boy down from the tree; he ordered Monkey to carry he boy on his back.

As they started to go, Red Boy jumped into mid-air, leaving behind a false Red Boy for Monkey to carry. To kidnap Sanzang, Red Boy hurled a whirl of wind at him. Sanzang disappeared.

Monkey knew this was done by the demon and he asked Pig and Friar Sandto look after the luggage and he hurried to the Huofang Cave in the Withered Pine Valley to look for his master. A fierce battle ensued between Monkey and Red Boy. Knowing it is impossible to defeat Monkey, Red Boy Spurted three types of flames which were so powerful even the Dragon King could not put out.

Monkey, knowing he could not win, jumped out of the sea of fire and went to the South Sea to ask the Goddess Guanyin for help. The goddess vanquished Red Boy and brought him to the South Sea. Monkey saved Sanzang and Sanzang and his disciples continued their journey to the West in search of Buddhist scriptures.
