我不知坚强是流泪
[wŏ bù zhī jiān qiáng shì liú lèi]
This name expresses a sense of inner conflict. 'I Do Not Know If Being Strong Is to Cry' implies someone who struggles with showing strength but also has moments where they can't hide their emotions. It's like not knowing if expressing weakness (by crying) can be considered another form of being strong.
