Zhāng Gāng 張綱 (1083–1166), zì Yànzhèng 彥正, hào Huáyáng lǎorén 華陽老人, native of Jīntán 金壇 (modern Jiāngsū). One of the four 廬陵 (or, more accurately for Jīntán, Jiāngzuǒ) Shàngshèfǎ champions: in the Dàguān / Zhènghé trial-of-the-school-method, he placed first in the Chóngzhèng hall, three times in succession at the head — a feat noted in the Sìkù tíyào and Hóng Mài’s preface. Initially obstructed by Cài Jīng 蔡京 and Wáng Fǔ 王黼; after the southward crossing he ran afoul of Qín Guì 秦檜 and was forced into retirement; recalled only after Qín’s death (1155). Reached Cānzhī zhèngshì 參知政事 (Vice Grand Councillor). Posthumously honoured Tàishī, Qínguógōng, shì Wénjiǎn 太師、秦國公、諡文簡. CBDB id 252 confirms 1083–1166.
His literary collection Huáyáng jí 華陽集 KR4d0159 in 40 juǎn (with 10-juǎn fùlù in some recensions) was nearly destroyed in the Jiànyán 1130 (gēngxū 庚戌) Jīn invasion — Hóng Mài’s preface records that only one in a hundred pieces survived the burning of Zhāng’s Jīntán family library. His son Zhāng Jiān 張堅 reassembled some 859 pieces; his grandson Zhāng Fǔ 張釜 (Prefect of Chízhōu) eventually undertook the printing in Shàoxī 2 (1191), with the preface by Hóng Mài.
The catalog meta gives 1083–1166 and CBDB confirms; no correction needed. Zhāng was prolific in court drafting and jiǎngyán gùshì 講筵故事 (court lecture pieces) — Hóng Mài’s preface enumerates 19 pieces from this latter category as the most striking part of the collection. Zhāng is also notable for opposing the over-rehabilitation of Yuányòu descendants under early Southern Sòng, on the principle that the dǎngjí recompense had become indiscriminate.
