不怕刺耳讽笑只怕自己投降
[bù pà cì ĕr fĕng xiào zhĭ pà zì jĭ tóu jiàng]
This means 'I'm not afraid of harsh jeers, but fear submitting to my own'. It indicates a state of strong spirit and willpower that overcomes self-doubts, more so than societal criticism. This shows courage to confront adversity but a struggle against surrendering within oneself.
