笑只是逞强
[xiào zhĭ shì chĕng qiáng]
'Laughter is Just Bravado' shows an attitude towards smiling as a facade. Sometimes, in difficult situations, people put up brave and strong fronts. Behind such laughter, it may be that the person feels lonely inside and tries to hide real inner pain through laughing. Users with such usernames tend to suggest their inner emotions don’t entirely match their surface behavior; rather, the latter can be seen as a defense mechanism or mask.
