On the day he was laid off, Shen Yideng caught his fiancé cheating on him and received an obituary notice from his grandmother.
At thirty-two years old, she seemed to have been rejected by life.
She returned to the ancient town of Wannan to guard the lamp shop. She wanted to sell the shop and leave, but in the century-old lamp, she met a person who was slowly disappearing - A Zhu.
The ancestral precept said: Only if the ever-burning lantern does not go out for three years can the store be transferred. But what this lamp burns is not oil, but "heart fire" - every time she repairs an old lamp that carries obsessions for someone, he becomes clearer.
The revolving lantern replayed the unfinished words of the deceased mother, and the river lantern said the late "I'm sorry" to the mute girl. A lamp that cannot be repaired is because its owner is still alive, but his heart has become cold...
Repairing lamps turns out to be repairing people's hearts. She lights up others and also shines upon herself.
But she gradually understood: What A Zhu really wanted was not to live - but to die out decently.
And she wanted to keep a person who was bent on death.
