空城一生半世殇寂寞一生半心慌
[kōng chéng yī shēng bàn shì shāng jì mò yī shēng bàn xīn huāng]
Translated as 'A Lifetime in An Empty City, Half-Life Sorrow Loneliness Half Life Anxiety'. This indicates the pain of living in isolation, experiencing both loneliness throughout much of life and moments of anxious unease.
