少年的泪不及海水蓝少女的笑不及阳光暖
[shăo nián de lèi bù jí hăi shuĭ lán shăo nǚ de xiào bù jí yáng guāng nuăn]
This poetic phrase contrasts 'a young boy's tears don't compare to the blue sea' and 'a girl’s smile cannot match up to the warmth of sunshine'. It metaphorically explores the bittersweet nature of young lives and love, portraying both depth and beauty.
