Chén Shīshèng 陳師聖 (correctly read as 李師聖 Lǐ Shīshèng per Chén Zhènsūn’s Shūlù jiětí; fl. late Northern / early Southern Sòng), Sòng-period scholar of Púyáng 濮陽. Discovered 21 piān of an old anonymous Chǎn lùn (Discussion on Childbirth) — discussions only, with no prescriptions — to which the contemporary Imperial Medical Academy Professor (醫學教授) 郭稽中 Guō Jīzhōng appended prescriptions, completing the work as the Chǎnyù bǎoqìng jí 產育寶慶集 (KR3e0040, 2 juan). The catalog meta lists Chén Shīshèng but Chén Zhènsūn gives the surname as Lǐ — likely a transcriptional error. Lǐ Shīshèng has no further transmitted biographical record.
