At the age of forty Tan Sheng was without a wife. He often became aroused through study and reading. Suddenly one midnight a young woman appeared to him, aged fifteen or sixteen and peerless under heaven in her appearance, dress and posture. She came to Sheng so they could be husband and wife, but told him: “I am not like other people. Never let firelight shine upon me. Only after three years have passed may I be illuminated.” They then lived as man and wife. She’d bore a son, who was already two years old, when, unable to bear it any longer, Sheng waited until she was asleep then stealthily illuminated and examined her. Above her waist was living flesh, just like any human being, but below her waist were just dry bones. His wife awoke, and told him: “The gentleman has betrayed me. I had almost returned to life – why could you not bear to wait just one more year before examining me?” Sheng parted from her with thanks, weeping, as they could no longer be together.
She said: “Although my parting from the gentleman is entirely correct, I am still concerned for our child. You are poor and unable to support yourselves, so follow me a moment and I will leave you something of value. Sheng followed her as she entered a splendid hall, its rooms and furnishings all quite extraordinary. Indicating a pearl-stitched gown, she handed it to him and said: “You can support yourself with this.” She then tore away the front of the gown, left it with him and departed. Sheng subsequently took the robe to the market, where it was purchased by the household of the Suiyang Prince, earning him a thousand ten-thousand strings of cash.
The prince recognised the robe, however, and said: “This is my daughter’s gown. It must have been taken from her tomb.” He thus seized and beat Sheng, who told him the full truth, but the prince still did not believe him. They therefore went to view the tomb, and found the grave undisturbed, just like  before. When they opened it, beneath the coffin lid they found the same gown. They called his child, and indeed he resembled the princess. The prince then believed the story, and summoned Tan Sheng, granting him the gown and installing him as princely consort. Their son was appointed Chancellor.
