入木三分侵心七尺
[rù mù sān fēn qīn xīn qī chĭ]
A classical Chinese saying describing words or art that penetrate deeply, implying piercing observations. It metaphorically conveys intense impact or emotion reaching the core of one's heart (three-finger deep into wood, seven-finger deep in heart). The name represents powerful insight into human emotions or matters and emphasizes significant, moving influence. Aesthetically, such depth is associated with profundity in feelings or experiences.
