Tóngjiāng Yīng 桐江瑛
Sòng-period Vinaya / zhǐguān master (lifedates not preserved), author of the Guānxīn míng 觀心銘 (“Mind-Contemplation Inscription”) appended as a fùlù in 性祇 Xìng Qí’s Píní rìyòng lù (KR6k0258), where the work is cited as a staple of the late-Míng Vinaya xíngchí 行持 curriculum. The 桐江 prefix is a place-style (lit. “Tóng-river”, a Zhèjiāng locale); “Yīng” is the single-character given dharma-name. No independent biography preserved.
