本文對新出長孫祈墓誌進行了錄文，並做了初步研究。誌主長孫忻出身北魏「帝之十族」長孫肥家。曾祖長孫汗即《魏書》中的長孫翰，祖父長孫侯即《魏書》中的長孫渴侯，在文成帝即位之際立有大功，旋即被殺。父親長孫德曾任中山王元英副將，長孫忻本人於孝文帝末年起家，長期任職於禁衛系統，推測當死於孝明帝初年禁衛系統反對元叉專權的某次未遂政變之中。墓誌中出現了兩處罕見記錄的北魏軍鎮度斤鎮與賀侯延鎮，度斤鎮或即武川鎮。

The epitaph of Zhangsun Xin was unearthed in the Luoyang region in recent years. Through research on this epitaph from the Northern Wei dynasty, the author shows that Zhangsun Xin belonged to the Zhangsun Fei clan in the Wei Shu (魏書). This clan occupied a special place in the system of the imperial guards, from the Pingcheng era to the Luoyang era. The epitaph also records Dujin Town (度斤鎮) and Hehouyan Town (賀侯延鎮), providing some clues about military towns in the Northern Wei.
