时间偷走初衷只留下了苦衷
[shí jiān tōu zŏu chū zhōng zhĭ liú xià le kŭ zhōng]
This translates to 'Time has stolen the initial aspirations, only leaving behind bitterness'. It expresses sadness or regret that time changed things, making an idealized original goal unachievable and replaced with grievances or resentment.
