Zeng Di was a Song dynasty ci poet whose biographical details are limited: his birth and death years, native place, and official career are not well documented and remain difficult to verify. The library holds one work attributed to him, a collection of ci poems titled Haiye Ci, commonly classified under classical poetry. This indicates that Zeng Di was known to later generations chiefly through his ci compositions, which were gathered and transmitted in this collection. The poems in Haiye Ci largely treat everyday feelings and the contemplation of scenery; their language is graceful and melodious, showing the typical character of Song literati ci. Because relevant historical sources are scattered and lost, Zeng Di's specific place and influence in the history of ci still require further study, yet Haiye Ci, as his surviving work, offers useful material for understanding the creative landscape of Song dynasty ci and gives readers a way to appreciate this poet's stylistic orientation.
