心脏往里一寸的地方
[xīn zàng wăng lĭ yī cùn de dì fāng]
Literally meaning 'an inch inside the heart', it's a very poignant way of referring to the deepest part of oneself, close to the core of human emotion or soul. It suggests introspection into very personal, possibly painful, yet also valuable aspects within oneself.
