Duke Xi

1. First remember that Duke Xi of Lu and Duke Xi of Qi belong to two different states, then sort out each one's place in his lineage.
2. Compare with the relevant years in the Zuo Zhuan to restore the brief introduction to concrete events.
3. When reading the section on Duke Xi of Lu, note the relation between his thirty-three-year reign and Lu's national strength.
4. When reading the section on Duke Xi of Qi, understand it together with Qi's situation before Duke Huan took the throne.

Jinzhang Book Company (Jinzhang Shuju) was a private publishing and distribution house in Shanghai during the late Qing and early Republican periods, issuing traditional works by lithographic printing. Judging from the 1,194 titles in the collection, its publishing focused on classical poetry, Eastern philosophy, historical reading, traditional Chinese medical texts, and canonical works, along with books on literary appreciation. Representative titles include the poetry and prose collections of Du Fu and Ouyang Xiu; historical works such as the Book of Han and Zizhi Tongjian; classical texts such as the Book of Documents and Mencius; and specialized and literary classics such as Treatise on Cold Damage and Li Sao. Its author resources cover major figures across the ages, including Du Fu, Ban Gu, Sima Guang, Zhang Zhongjing, Qu Yuan, Ouyang Xiu, and Tang Shenwei, reflecting the house's characteristic reliance on traditional scholarship and medical literature while serving general readers. Public information on its early history and operational details is limited, so no conjecture is offered here.
