Lǐ Chuò 李綽 (fl. late ninth century, lifedates uncertain), zì Jiānmèng 肩孟. Of the Zhàojùn 趙郡 (Héběi) Lǐshì Nán zǔ (southern progenitor) line, great-grandson of Lǐ Shū 李紓 (Lìbù shìláng) per the Xīn Táng shū Zǎixiàng shìxì biǎo. Took refuge at Pǔtián 圃田 in Hénán during the Huáng Cháo rebellion of 880–884. Compiler of the Shàngshū gù shí 尚書故實 (KR3j0084), a 1-juan late-Táng connoisseur’s miscellany recording the family-traditions and connoisseur’s knowledge of a senior Zhāng-clan shàngshū (identified by the SKQS editors as falling within the Zhāng Yànyuǎn / Lìdài mínghuàjì generation). The catalog meta gives a c. 805–862 date-range, corresponding to the earlier-Lǐ-Chuò identification; this is not adopted in the work-note frontmatter, which follows the SKQS editors’ later identification.
