你不懂我撕心裂肺你不懂我欲哭无泪
[nĭ bù dŏng wŏ sī xīn liè fèi nĭ bù dŏng wŏ yù kū wú lèi]
'Ni Bu Dong Wo Si Xin Lie Fei, Ni Bu Dong Wo Yu Ku Wu Lei' means 'You don't understand how torn and shattered I am inside; you don't understand my desire to cry but having no tears left,' expressing overwhelming emotional anguish and lack of understanding from others.
