你又不是我怎会懂我
[nĭ yòu bù shì wŏ zĕn huì dŏng wŏ]
Translated as 'You are not me, how can you understand me'. This internet name reflects a sentiment where the user feels that no one but oneself could truly understand the feelings they experience, implying an unshared and perhaps isolating personal understanding or experience that others fail to grasp due to not having experienced it from their point of view.
