Yáng Liàng 楊倞 (fl. early 9th c.) was a mid-Táng official of the Hóngnóng 弘農 Yáng lineage who completed his commentary on the Xúnzǐ 荀子 in Yuánhé 元和 13 (818). His preface notes that he undertook the work “in the leisure of a junior office” because while the Mèngzǐ had Zhào Qí’s 趙岐 Zhāngjù 章句 and an established Hàn-era bóshì tradition, the Xúnzǐ alone lacked a commentary, and the bamboo strips were corrupted and miscopied to the point that even sympathetic readers gave up midway. He divided the old twelve-juan / thirty-two-篇 text into twenty juan, rearranged the order of the chapters into thematic groups, and renamed the work Xúnzǐ (the Hàn title had been Sūn Qīng xīnshū 孫卿新書). The Xīn Táng shū yìwén zhì identifies him as the son of Yáng Rǔshì 楊汝士, but the Zǎixiàng shìxì biǎo in the same history lists Rǔshì’s three sons as Zhīwēn 知溫, Zhīyuǎn 知遠 and Zhīzhì 知至, with no Liàng — the SKQS tíyào speculates that Liàng may simply be a name change, on the model of Wēn Tíngyún’s 溫庭筠 also being known as Wēn Qí 溫岐. CBDB id 196254 (one of two homonyms) carries a fl. latest of 875 but no firm dates; the secure datum is the 818 preface. He is responsible for the standard pre-Qīng commentarial layer on the Xúnzǐ (KR3a0002).
