心事是躲在喉里的血
[xīn shì shì duŏ zài hóu lĭ de xuè]
'心事是躲在喉里的血' is poetic imagery that signifies hidden distress or worries. The idea of blood suggests a depth or severity; emotions being trapped somewhere within—here in the throat—that may not fully be vocalized. Such hidden pains could come out, much like blood can force itself to escape if kept too long.
