Ruler of Luoyang Chen Quan-chong meets nephew Chen Shi-in, who is going to the capital for an exam. At night, when a young man indulges in wine and music, the heavenly (living on the Moon) virgin Cinnamon flower with his friends comes to him. She fell in love with the young man because his music saved her from evil stars during a lunar eclipse. The young man and the maiden feast and have mercy. Leaving, she promises to come exactly one year later - on the 15th day of the 8th month.

Almost a year has passed. Chen falls ill from separation. Uncle sends an old maid to him, but she is not able to alleviate his suffering.

Insert. A doctor comes, a farcical scene is played out. Chen continues to suffer.

To the ruler comes to say goodbye, the Taoist high priest Zhang Dao-xuan. Noticing that there is a patient in the house, he visits Chen and sees that he is tormented by obsession. By the power of magical art, he calls the celestials in turn - Plum, Peach, Lotus, Chrysanthemum ... then the deities of Thunder, Snow ... They all deny their guilt. Finally, the Cinnamon Flower appears. She accuses the sins of all other celestials, trying to whitewash herself. Everyone goes to the judge, Longbrowed Saint.

The long-browed reproaches the maiden for debauchery and harm done to the young man.But since she did this without malicious intent, the saint pities the virgin, saves her from punishment and returns to the moon. He sends the other celestials back.
