Heavy snow has sealed the ancient city wall, and the leaden gray clouds are very low, like a piece of water-soaked cotton wool, covering heavily in the sky above Zhuque Street.
Su Wan wrapped her body in an off-white down jacket, her fingertips were red from the cold, but she still held a yellowed thread-bound book and stood in front of the restoration room window of the Shaanxi Provincial History Museum.
Inside the glass, her mentor was carefully picking up a broken piece of silk paper with bamboo tweezers. It was a cultural relic that had just been unearthed from a Tang tomb. According to research, it was a note from an unknown scholar in the mid-Tang Dynasty. The ink was so faint that it almost blended into the years, but the words "Chang'an Snow, I will return far away, I remember you" can be vaguely discerned.
Su Wan is a graduate student in the History Department of Peking University, specializing in the social and cultural history of the Middle Tang Dynasty. She has been in Xi'an for three months for this note. She always feels that those words that have been sleeping underground for thousands of years contain unsaid stories and obsessions that transcend time.
"Xiao Su, it's time to get off work. The snow is too heavy." A colleague's voice came from behind, with warmth.
