心早就已经痛到麻木
[xīn zăo jiù yĭ jīng tòng dào má mù]
The title translates to 'Heart Has Already Pained into Numbness,' describing extreme emotional pain so intense it has become almost commonplace to the bearer. It conveys feelings like profound sorrow from continuous suffering which eventually leads to an emotional dulling or detachment as a coping mechanism.
