When astronomy intern Lin Shuxing plunged into the ancient city of Pingyao, he thought it was a publicly funded tourist survey to map the solar eclipse, but instead he stepped into a strange mystery deep in the ancient city.
In the attic of the old house opposite, a silent "light show" is staged every night - not lights, but swarms of fireflies. They flicker behind the blinds, and the ancient star map codes are actually outlined in the gathering and dispersing! And the "mastermind" behind all this was actually a taciturn, ancient book restorer who wore a moon-white gown and was said to be mute.
What's even more strange is that he appears on time at the bluestone bridge every night and ties a bouquet of aster flowers to the bridge railing. Is it an affectionate confession? Or a silent memorial?
The scientific brain's curiosity was completely ignited. She uses telescopes, notebooks, and star chart software to solve the riddle of this ancient city that spans time and space and is constructed of fireflies and silence.
From the initial observer to exploring the star ruins of the ancient city side by side, she gradually entered his silent world. When the star trails in ancient books began to resonate with the heartbeats of reality, when the secrets hidden in history and starlight were gradually revealed... The man who had silenced the entire world finally wrote the only "line" in the palm of her hand in the most gentle way on that beautiful moonlit night.
This is a story about ancient cities, stars, lost languages, and the most sincere love and waiting that bloom in silence.
