他不是太阳却暖进我心她不是钻石却光耀万照
[tā bù shì tài yáng què nuăn jìn wŏ xīn tā bù shì zuàn shí què guāng yào wàn zhào]
He's Not the Sun but Warms My Heart; She's Not a Diamond but Shines Bright. This reflects a profound appreciation for someone who brings warmth and light into one's life despite not being the most dazzling.
