Principles of War is a reference to Sun Tzu’s
The Art of War, a widely influential Chinese work on military strategy. This helps Kuang introduce readers to factual Chinese history, in addition to that of fictional Nikan. While Trengsin seems almost superhuman and is obnoxiously competent, Master Jiang—the Lore master—is obnoxiously
incompetent. His eccentric behavior here suggests that Rin and her classmates actually don’t have anything to learn from him, an idea that the novel will go on to question.
