Sūn Dí 孫覿 (1081–1169), zì Zhòngyì 仲益, hào Hóngqìng jūshì 鴻慶居士, native of Jìnlíng 晉陵 (modern Chángzhōu 常州, Jiāngsū). Born Yuánfēng xīnyǒu 元豐辛酉 (1081); jìnshì and cíkē champion. The Sìkù editors describe him as a qiānwàn rén zhōng shí yī yù (one-in-a-thousand) talent — a major figure who lived nearly 90 years (89 suì at death) across a wide span of Northern-and-Southern Sòng.
Career: under Huīzōng / Qīnzōng — zhífǎ (censorial) and cíchén (drafter) office; passed through suǒtà (drafting bureau) up to Lìbù and Hùbù posts; prefect of large commanderies. Under Shàoxīng he was implicated in kǒuyǔ (mouth-talk, i.e. malicious gossip) and banished to Xiàngjùn 象郡 (Lǐngnán). After return retired to the Tàihú lakeshore, where he lived for 24 years (èr jì = two duodenary cycles).
Under Xiàozōng once commanded to compile records of the Cài Jīng / Wáng Fǔ era — submitted to the historiographical bureau (a gùshì parallel to Fúshēng of the Hàn).
Memorialised: even past 87 he composed his own xièbiǎo (memorials of thanks) — Zhōu Bìdà’s preface (dated Qìngyuán 5 = 1199, by Zhōu’s own retired-prime-minister-and-Yì-guó-gōng age 73) records that on encountering Sūn at Yángxiàn (= Yíxīng) when Sūn was 87, the conversation was jiànlùn tāotāo rú Hónghé dōngzhù (vigorous-discussion flowing-on like the Yellow River pouring eastward).
CBDB id 7343 confirms 1081–1169.
His collection is Hóngqìng jūshì jí 鴻慶居士集 KR4d0179 in 42 juǎn (compiled by his sons Sūn Xīngguó 孫興國, Sūn Tàizōng 孫太宗, and Sūn Jièzōng 孫介宗 from surviving drafts; the original was much-damaged in bīngjìn (war-fires)). The Fújiàn and Sìchuān prints had erroneously incorporated Zhái Zhōnghuì (= Zhái Rǔwén 翟汝文 翟汝文 of KR4d0150)‘s prose with Sūn’s, hence the family’s care to redefine the corpus.
Sūn also has the Nèijiǎn chǐdú 內簡尺牘 KR4d0180 in 10 juǎn — a pupil-edited annotated letter-collection.
