一世薄凉
[yī shì bó liáng]
'A Life of Futility' describes someone feeling a sense of emptiness or pointlessness in their entire life. '薄凉' here expresses coldness and vanity, indicating a world that appears bleak and indifferent or even full of indifference and neglect, thus this username may reflect a pessimistic or disillusioned view on life.
