Shen Deng is the intangible inheritor of shadow puppetry. There is a strange "soul shadow" hidden in the old shadow puppet box left by his grandfather - whenever she plays "Farewell My Concubine", the shadow puppet Xiang Yu's eyes will ooze red tears. Until she was repairing a damaged Yu Ji shadow puppet, her fingertips touched the cinnabar mole on the shadow puppet's forehead, and she suddenly saw her grandfather's memory: He was sewing a strand of hair into the shadow puppet, and said "The soul returns to the shadow, and the lamp will be kept for a hundred years."
What's even more bizarre is that late at night after the performance, singing will come from the shadow puppet box. When the box is opened, Yu Ji's shadow puppet actually stands on the stage. An old artist in the village told her: "The Shen family's shadow puppets can hide people's souls. Your grandfather was trying to keep the 'soul' of shadow puppets." That night, Shen Deng found his grandfather's diary on the bottom of the shadow puppet box. On the last page, there was a cinnabar mole of the same style as Yu Ji's shadow puppet, and a light red mole slowly appeared in the corner of her eye.
