Cháo Guànyī 晁貫一
Northern-Sòng official and ink-connoisseur of the great Cháo family of Jūshī 鉅(濟)-野 (Shāndōng). Zì Jìyī 季一. Brother (xiōngdìháng) of Cháo Shuōzhī 晁說之, hence cousin or kinsman of Cháo Buzhī 晁補之, Cháo Yǒngzhī 晁詠之, and Cháo Chōngzhī 晁沖之 — the prolific “Cháo brothers” of the Yuányòu–Chóngníng period. Office reports him as jiǎntǎo 檢討 (compiler) on one occasion and as cháyuàn 察院 (censorial-office) on another (per Zhū Biàn’s 朱弁 Fēngyuè táng shīhuà); his final post is not recorded.
His one substantial work is the Mòjīng 墨經 (KR3i0011), one of the three principal Sòng monographs on ink (alongside KR3i0010 by Lǐ Xiàoměi and KR3i0012 by Lù Yǒu). The work is firmly attributed to Cháo Jìyī (= Guànyī) by Hé Wèi 何薳 in the Chūnzhǔ jìwén 春渚紀聞: Hé Wèi reports that Cháo Jìyī had no other tastes save a love of ink, that he had his own studio name Jìjì xuān 寄寂軒 used as his ink-mark, and that he was reputed to have closely studied the methods of glue-blending alongside Hè Zhù 賀鑄 (Fānghuí 方回), Zhāng Bǐngdào 張秉道, and Kāng Wéizhāng 康為章. Sòngshǐ gives no separate biography.
