Late-Míng / early-Qīng textual critic of Chángshú 常熟 (Sūzhōu, Jiāngsū). CBDB id 30245, dates 1593–1649. Zì Jǐcāng 已蒼; hào Mòān 默庵. Brother of Féng Bān 馮班 (1602–1671), also a noted textual critic. The brothers were active in the Wǔzhōng Chángshú scholastic culture — alongside Mao Jìn 毛晉 of the Jígǔgé — that pioneered systematic textual collation through appeal to Sòng imprints.
Féng Shū’s principal independent work is the KR4h0108 Shījì kuāngmiù 詩紀匡謬 (1 juǎn) — a 112-entry textual-critical correction of 馮惟訥 Féng Wéinè’s KR4h0107 Gǔshī jì. The two works are paired in the Sìkù as mutually-supplementary, standard recension + textual corrections — a unique pairing in the corpus. He also collaborated with Féng Bān on a much-cited critical edition of the Yùtái xīnyǒng 玉臺新詠 (the Féng-brothers’ edition), and his marginalia on Táng poetry (the Féng commentary on the Cáidiào jí 才調集) was used by Wáng Shìzhēn 王士禎 and other Qīng critics.
