曾经只是曾经
[céng jīng zhĭ shì céng jīng]
'Zeng Jing Zhi Shi Zeng Jing' can be translated as 'the past is just that - the past.' By adopting this as their online identity, an individual suggests they understand everything has passed cannot be changed, reflecting a somewhat nihilistic or resigned viewpoint on the irreversible passage of time.
