Zhā Shènxíng 查愼行 (1650–1727), zì Xiàzhòng 夏重, hào Chūbái 初白 — calling himself Chūbáiān zhǔrén 初白菴主人. Of Hǎiníng 海寧 (Zhèjiāng). Kāngxī guǐwèi / 1703 jìnshì; held office as Hànlínyuàn biānxiū. Eminent early-Qing poet — counted among the principal “Zhèpài” (Zhejiang school) figures alongside Zhū Yízūn 朱彝尊 and Wáng Shìzhēn 王士禛 (Yúyáng); prolific biéjí (his own Jìngyètáng shījí 敬業堂詩集 in 50+ juǎn). Devoted three decades (癸丑 / 1673 to Kāngxī rénwǔ / 1702) to the production of his Sūshī bǔzhù 蘇詩補註 KR4d0081 in 50 juǎn — the principal Qing supplement to the parallel Shī Yuánzhī / Shào Chánghéng tradition KR4d0080 and to the Wáng Shípéng bǎijiā tradition KR4d0077. The Sìkù tíyào ranks Zhā’s annotation as the foremost — zìyǒu Sū shī yǐlái zhùjiā yǐ cǐ běn jūzuì (since the existence of Sū’s poetry, of all annotators this is the foremost). The Sūshī bǔzhù methodology is biānnián (chronological) — placing Sū’s poetry in fully reconstructed travel-and-office sequence, with an integrated niánpǔ. CBDB id 694427.
