Tán Shànxīn 譚善心 (fl. 1320s)
A Yuán-period scholar of Línchuān 臨川 (modern Jiāngxī, the SòngYuán literary heartland). In Zhìzhì 至治 (1321–1323) he undertook a major revision of the Èr Chéng wénjí 二程文集 KR4h0031 — Hú Anguó’s Southern-Sòng compilation of the prose and verse of the Chéng brothers (Chéng Hào and Chéng Yí) — in consultation with the Shǔ scholar Yú Pán 虞槃. Tán’s version restored the passages cut from the Hú Anguó / Liú Gǒng / Zhāng Shì redaction (in the Dìngxìng shū, the Míngdào xíngshù, and the Shàng Fùgōng xièshuài shū) by comparison with other surviving copies, added 16 extra prose pieces and 11 additional yíshì anecdotes, and appended Zhū Xī’s critical correspondence on the Hú Anguó text as a separate volume. The Tán redaction became the standard form of the Èr Chéng wénjí and is the basis of all later printings. No further biographical detail recoverable; no CBDB entry.
