The King of Huai Nan
The King of Huai Nan was a learned man of the Han dynasty. Since he was of the blood royal the emperor had given him a kingdom in fee. He cultivated the society of scholars, could interpret signs and foretell the future. Together with his scholars he had compiled the book which bears his name.
One day eight aged men came to see him. They all had white beards and white hair. The gate-keeper announced them to the King. The King wished to try them, so he sent back the gate-keeper to put difficulties in the way of their entrance. The latter said to them: “Our King is striving to learn the art of immortal life. You gentlemen are old and feeble. How can you be of aid to him? It is unnecessary for you to pay him a visit.”
The eight old men smiled and said: “Oh, and are we too old to suit you? Well, then we will make ourselves young!” And before they had finished speaking they had turned themselves into boys of fourteen and fifteen, with hair-knots as black as silk and faces like peach-blossoms. The gate-keeper was frightened, and at once informed the King of what had happened. When the King heard it, he did not even take time to slip into his shoes, but hurried out barefoot to receive them. He led them into his palace, had rugs of brocade spread for them, and beds of ivory set up, fragrant herbs burned and tables of gold and precious stones set in front of them. Then he bowed before them as pupils do before a teacher, and told them how glad he was that they had come.
The eight boys changed into old men again and said: “Do you wish to go to school to us, O King? Each one of us is master of a particular art. One of us can call up wind and rain, cause clouds and mists to gather, rivers to flow and mountains to heave themselves up, if he wills it so. The second can cause high mountains to split asunder and check great streams in their course. He can tame tigers and panthers and soothe serpents and dragons. Spirits and gods do his bidding. The third can send out doubles, transform himself into other shapes, make himself invisible, cause whole armies to disappear, and turn day into night.
