During the Zhenguan period, Chang'an's Zhuque Street was bustling with traffic, and the ordinary alleys concealed various flavors of the world. She came from the south of the Yangtze River and brought with her an unknown secret - she could see "phantoms" wandering between the streets and palace walls. These shadows are neither ghosts nor immortals. They are lingering obsessions, unfinished wishes, and glimmers of light leaking from the folds of history. Some are attached to old things, telling anecdotes from the past; some linger in the market, guarding unfinished worries. When she was listening to a book in a teahouse, she could see a shadowy figure in armor standing next to the storyteller; when she was buying flowers in the Western Market, she could catch a glimpse of a weeping woman lingering next to the flower stall. She does not indulge in illusions, nor is she trapped in reality. She uses the fireworks of the world as an anchor, walks between phantoms and reality, and helps her obsession find a home. In the process, she understands the weight of Chang'an and the warmth of human feelings, and slowly lives a real and ethereal scenery in Chang'an city.
