抹不去的伤拭不去的痛
[mŏ bù qù de shāng shì bù qù de tòng]
This translates to 'Scars that won’t fade away, and pain that won't subside'. This indicates that the person may have been hurt and finds it difficult to get over that hurt. Often used when someone suffers deep emotional wounds or loss which takes time to recover from.
