Set in Beijing in September 1998, the novel opens by capturing the distinctive mood of late summer turning to early autumn. Leaves fall from the locust trees beside Weiming Lake, and the scene of new students arriving brims with youthful energy. The story unfolds when Chen An, a freshman, happens to meet Zhou Xing, a graduate student. Clutching a hefty copy of A History of Western Philosophy, Zhou Xing hurries to submit paperwork at his department. His sunny, outgoing nature and slight air of apology leap off the page. Their conversation about books reveals Zhou Xing's deep engagement with philosophy, while hinting at the exchange of ideas and collision of minds between them.
The story that follows may center on Chen An and Zhou Xing's encounters on campus. In an environment alive with youthful energy and intellectual exploration, they may influence each other in their studies and pursuit of ideals, while gradually developing a deep bond in their daily lives. Perhaps it will be friendship, or perhaps love. Together, they may experience the story of youth that belongs to their era, facing the doubts, choices, and transformations that come with growing up.
