Dài Zuò 戴祚 (late 4th century), sparsely attested late-Eastern-Jìn writer. No standard biography in the Jìn shū; he is known only from the Suí shū jīngjí zhì 隋書經籍志 attribution of the Zhēnyì zhuàn 甄異傳 / Zhēnyì jì 甄異記 in 3 juàn to him, with corroborating entries in both Táng bibliographic treatises. Some Sòng léishū citations identify him as Tàizǐ shērén 太子舍人 (“Companion to the Heir Apparent”), but the attribution cannot be securely cross-checked. He is conventionally placed in the late Eastern Jìn (c. 380–420), contemporary with Zǔ Táizhī. He has no CBDB id in the current dump.
Within the Kanripo corpus he is the credited author of KR3l0164 Zhēnyì jì.
