影子与我相伴到老
[yĭng zi yŭ wŏ xiāng bàn dào lăo]
'Shadow accompanies me until old'. It reflects on how the only consistent companion might be something as insubstantial yet ever-present as one’s shadow. This nickname could hint at loneliness, introspection, acceptance of solitude or being at peace with one's self-companionship
