你送我一米阳光我给你一片暖阳
[nĭ sòng wŏ yī mĭ yáng guāng wŏ jĭ nĭ yī piàn nuăn yáng]
This translates as 'You give me a meter of sunshine, I give you a warm sunlight.' It implies an exchange of kindness and warmth between two people. If someone gives them happiness (sunshine) then they will repay it in greater abundance (a warm sun).
