Shì Dàocàn 釋道璨 (1213–1271), also written 道燦, zì Wúwén 無文 (“Without-Letters” — a Chán self-naming), hào Liǔtáng 柳塘 (“Willow-Pond”), with lay surname Táo 陶, was a late-Sòng Línjì 臨濟 Yángqí 楊岐 Chán monk of Tàihé 泰和 in Jí’ān 吉安 (Jiāngxī). He was the Dharma-heir (fǎsì 法嗣) of Xiàowēng Miàokān 笑翁妙堪 (1177–1248) of the great Yùwángsì 育王寺 in Míngzhōu 明州, in the 19th generation from the Sixth Patriarch (大鑑下第十九世). The DILA authority record (A008958) gives 1213–1271; CBDB (34892) records him with the surname Táo but without confident lifedates, marking only fl. 1248 from the Sòng yī shìzhě xù internal evidence. He was installed as abbot of the Jiànfúsì 薦福寺 at Ráozhōu 饒州 in Bǎoqìng 3 (1227), moved to Kāixiān 開先 on Lúshān 廬山, and returned to Jiànfú in Shàodìng 2 (1229). He died in Xiánchún 7 (1271) at the age of 59 (Wǔdēng quánshū 五燈全書 53; Wǔdēng huìyuán xùluè 五燈會元續略 2; Sòngsēng zhù 宋僧著: 571). His one Dharma-heir was Yúsǒu Chéngjiàn 愚叟澄鑑.
Two principal works survive: his recorded sayings, Wúwén Dàocàn chánshī yǔlù 無文道燦禪師語錄 in the Xùzàngjīng 續藏經 (X69 no. 1372); and the secular-prose-and-verse collection, KR4d0380 Liǔtáng wàijí 柳塘外集 — preserved in the Sìkù quánshū, recovered from a unique Sòng manuscript by Shì Dàléi 釋大雷 in the jiǎyín of Kāngxī (1674) and re-engraved. The companion Wúwén yìn 無文印 in 20 juàn (held at the Shànghǎi Library and at Běijīng University Library) is a separate prose collection not received into the Sìkù. Of the Wàijí the most famous piece is the 1248 Sòng yī shìzhě xù 送一侍者序, a farewell-preface for a Japanese monk returning home after six years in Sòng China, often cited in modern scholarship on mid-13th-century Sòng-Japan religious exchange.
