坚强逞强
[jiān qiáng chĕng qiáng]
'Strong Pretender.' The user presents themselves as resilient and robust. However, this may involve a component of pretending or boasting to mask inner vulnerabilities. In other words, while seeming invincible or tenacious, one might still bear weaknesses that are not outwardly apparent. A dual-edged portrayal combining strength and defense mechanisms.
