你是我的眼泪与阳光你是我的笑容与太阳
[nĭ shì wŏ de yăn lèi yŭ yáng guāng nĭ shì wŏ de xiào róng yŭ tài yáng]
These poetic words compare someone special to various positive elements - the person who brings both tears (deep emotion or pain) and sunshine into one's life, just like the smile and sun give warmth and light.
