"The Mysterious Story of Xi'an Bell Tower Ghost Market" takes the mysterious ghost market of Xi'an Bell Tower during Qixi Festival as the core, and unfolds a supernatural adventure to protect the memory of the city. Legend has it that every Chinese Valentine's Day, the seams in the green bricks of the Bell Tower Road will crack, leading to the ghost market where only living people with "obsessed hearts" can be seen - this place is guarded by the obsessives of the "Chang'an Memory Department" of the Tang Dynasty, which stores the folk memory of Chang'an. Anyone who violates it will be devoured. Cultural and tourism editor Shen Yan lost her friend Lin Xiaoman in a ghost market by mistake. She teamed up with folklore graduate student Gu Zhaozhao to investigate and uncover the plot of the villain "Eclipse Hall" who wanted to refine "Forget Sichuan Pill" to erase the cultural context of Xi'an. The two joined hands with the city keeper Chen Bo to collect "memory jade" to awaken the bewitched obsessives, guarding the millennium context with supernatural power and tenderness, and finally turned the ghost market from a "devourer" to a "return of memory".
