Ráo Jièzhī 饒介之 (Yuán), son-in-law of Dīng Fù 丁復 and compiler of the Kuàitíngjí qiánjí 檜亭集前集 KR4d0499. Confined to this editorial role in the surviving record; the Sìkù tíyào documents his collection-work but provides no further biographical detail. Not to be confused with the better-attested YuánMíng calligrapher Ráo Jiè 饒介 (d. 1367), Línchuān, whose given name is single 介; the zhī 之 is in this case the second character of a two-character given name. Independent identification is hampered by absent CBDB and Yuánshǐ records.
