Bái Tǐng 白挺 (also and more commonly written Bái Tǐng 白珽; 1248–1328; CBDB id 10833 under 白珽), zì Tíngyù 廷玉, hào Zhànyuān 湛淵, was a SòngYuán transition literatus of Qiántáng 錢塘 (modern Hángzhōu, Zhèjiāng), with residence at the West Lake — a spring rising from Zhúshān flowed past his gate; he named it Zhàn yuān (“the Pellucid Spring”) and adopted the name as his hào. The catalog meta gives his name as 白挺 (with tǐng as in “straight, sticking-up”); CBDB and standard reference works give 白珽 (with tǐng as in “jade tablet, virtuous”). The two graphs are similar in form and the Sìkù editors may have followed a transmission with the tǐng graph; the tǐng (珽 jade-graph) reading is preferred in modern scholarship — but here we follow the catalog meta. Born in Sòng Lǐzōng Chúnyòu 8 (1248); on the fall of Sòng in 1276 he was 27. Under the Yuán he was recommended by Lǐ Kàn 李衎 and held office as Tàipínglù rúxué zhèng, jiàoshòu, Chángzhōulù jiàoshòu, JiāngZhè děngchù tíjǔ, Huáidōng yáncāng dàshǐ, and finally Lánxīzhōu pànguān (retired thence). The Sìkù editors observe that his Sòng yímín self-styling is “jìntuì wú jù” (without firm ground in either advance or retreat), since he served the Yuán long. His one surviving work is the Zhànyuān jìng yǔ 湛淵靜語 (KR3j0137) in 2 juàn, compiled by his friend Zhōu Jiǎn 周暕 of Hǎilíng, with self-preface and Zhōu Jiǎn’s preface dated Zhìdà gēngxū (1310), when Bái was 63.
