坚强是别人不在意的东西
[jiān qiáng shì bié rén bù zài yì de dōng xī]
This username, translated to 'Toughness is something others do not care about', reflects a sentiment that inner strength or resilience goes unnoticed or unappreciated by others. This can symbolize a feeling of solitude, the struggle for recognition, or self-motivation even without external acknowledgment.
