我已薄凉成性
[wŏ yĭ bó liáng chéng xìng]
'I have turned cold-hearted by habit'. This suggests that over time, the individual has grown indifferent, possibly after facing various disappointments and challenges. Such apathy serves as a defense mechanism against further harm. Commonly, such expressions appear among young adults undergoing societal and emotional pressures, leading to a protective stance characterized by aloofness or guarded feelings toward others.
