坚强不是喊着坚强旳逞强
[jiān qiáng bù shì hăn zhe jiān qiáng dì chĕng qiáng]
Translated into 'Being strong does not mean boasting about how resilient one is'. By saying this as the nickname, people are usually trying to tell that real strength doesn't necessarily come with loudness or showing off courage and resilience outwardly; sometimes, true inner strength might lie quietly inside oneself. The person wants to express humility rather than bravado despite challenges faced within. This type of users tend to hide vulnerability well, facing adversity silently.
