我有煞笔我不悲
[wŏ yŏu shà bĭ wŏ bù bēi]
In Chinese slang, '煞笔' means an extremely stupid person or fool. The netizen seems to acknowledge his/her imperfections or even foolish mistakes openly and bravely while not succumbing to feelings of sorrow. This may mean he/she takes on life's challenges and laughs at his/her errors instead of letting them weigh him/her down with sadness.
