This entry refers to a collaborative work. Zu Yong (祖咏) was likely a monk who compiled or edited the text, Zhang Lun (张抡) wrote a preface (序), and Zong Yan (宗演) wrote a postscript or commentary (跋). Their specific periods are not definitively stated in this brief reference, but such collaborative scholarly endeavors were common in later imperial dynasties like the Song or Ming, often dealing with Buddhist canons or commentaries.
