左心房已停止跳动
[zuŏ xīn fáng yĭ tíng zhĭ tiào dòng]
Meaning 'The left atrium of the heart has stopped beating,' this carries a heavy metaphorical sense of loss. Given the left atrium is crucial for blood circulation, saying it has stopped might signify one's inability to love anymore, feeling emotionally dead inside due to significant grief or betrayal.
