Sū Zhòu 蘇籀 (1091–1164; CBDB id 1496), zì Zhòngzī 仲滋, was the grandson of the great Sòng essayist 蘇轍 (Sū Zhé, 1039–1112, hào Luánchéng 欒城) and the son of Sū Chí 蘇遲 (CBDB id 1495). A native of Méizhōu 眉州 (Sìchuān). After the Jīngkāng catastrophe and the Southern migration he settled at Wùzhōu 婺州 (Zhèjiāng); rose to Jiānchéng 監丞. From age 10 or so he attended on his grandfather Sū Zhé at Yǐngchāng 潁昌, never away from his side for nine years; he subsequently recorded what he had heard and could still remember in the Luánchéng yí yán 欒城遺言 (KR3j0114) in 1 juàn, intended for his descendants. The book is a major yǔlù-cum-bǐjì witness to Sū Zhé’s literary and political thought — in particular his theory of literary composition and his judgements on contemporary poets and statesmen — and a primary biographical source for the Sū family’s transmission. The book has been criticised (already by the Sìkù editors) for slight bias — privately favouring his grandfather over his great-uncle Sū Shì 蘇軾 — and for some preposterous fùhuì in the biographical anecdote (e.g. the jiāolóng tale of Sū Zhé’s birth, modelled on the two-dragon legend of Confucius). Sū Zhòu also produced poetry of his own, collected in the Shuāng xī jí 雙溪集.
