光我是黑夜暗我是白天
[guāng wŏ shì hēi yè àn wŏ shì bái tiān]
This phrase, translating to 'If I'm the night, darkness is my day', represents the duality within oneself – a reflection on embracing opposite sides within the individual’s personality or life experience, perhaps highlighting contrasts in daily routines or mood swings.
