他笑我不懂他我笑你的自信
[tā xiào wŏ bù dŏng tā wŏ xiào nĭ de zì xìn]
It translates to 'He laughs at my misunderstanding of him; I laugh at your confidence'. It reflects mutual incomprehension, self-assurance in differing interpretations, or perspectives on oneself versus others. Each side considers the other misinterpreted or overly assured.
