I've been thinking about this book a lot since I finished it, and the symbolism around books and covers is everywhere. Let me unpack it.
The Classic of Navigation from the Yin Dynasty—that's the MacGuffin of this whole sequence, right? It's priceless, ancient, fragile. Princess Yuyang throws it into the lake because it represents something Xie Zhi touched that shouldn't have been touched. But Xie Zhi had a DUPLICATE. She'd already removed the draft version from her robe before handing over the real one. The cover was damaged, but the book survived. I think that's on-the-nose symbolism for Xie Zhi herself—she's been damaged, thrown around by people like Yuyang, but she has layers and hidden strengths that protect her core.
Then there's the cloth book covers she sews. Pale green with ink-plum blossoms. She's essentially wrapping damaged things in beauty, making them presentable again. That's her whole survival strategy in this mansion. She can't fight Yuyang directly, so she makes herself useful, she charms Madam Yang, she wins over Pei Zhaoyin. She creates covers for people to see while hiding what's underneath.
And the name Lichun—"Spring Light"—given by Pei Du casually. Yuyang thinks it's a name Qi Songqing gave her as a token of affection. The misunderstanding itself is a kind of false cover, a misreading that destroys lives. Names matter in this world. They're labels that can trap you.
The deepest symbol though is probably the library itself. Guanxue Tower is where knowledge is kept, where servants can borrow books, where ancient texts are preserved. It's a space of learning and quiet power. Xie Zhi finds her agency there—through her skills, her knowledge, her ability to create. While the noble ladies float on boats admiring lotus flowers, she's in the library saving a dynasty-old manuscript with needle and thread.
This book is really about who gets to tell their story and who gets covered up instead.
