Legend has it that in ancient times, the Yellow Emperor fought Chi You nine times and lost every battle. He retreated to Mount Tai and hid there for three days and nights. At a loss for how to defeat Chi You, the Yellow Emperor knelt and prayed to Heaven.
Just then, a great deity appeared in the sky, with a human head and a bird's body, riding radiant clouds of seven colors. The Yellow Emperor bowed and begged the goddess to teach him the secret art of defeating Chi You.
With the goddess's teachings, the Yellow Emperor used the Qimen Dunjia and the Six Jia Yin-Yang Diagram to defeat Chi You.
It is said that the goddess who taught the Yellow Emperor magic was called the Nine Heavens Mysterious Maiden. From then on, the magical arts practiced by people were named after her, and so they came to be known as Mysterious Arts.
