努力认错死不悔改
[nŭ lì rèn cuò sĭ bù huĭ găi]
Translating roughly into 'striving to admit errors without remorse', this seemingly contradictory term actually reflects one having courage to accept their shortcomings while sticking to personal traits that others criticize. People adopting this nickname might possess a certain rebellious spirit and a strong sense of self-confidence, even against external judgment.
