我做太阳给你光让你暖
[wŏ zuò tài yáng jĭ nĭ guāng ràng nĭ nuăn]
This translates to 'I will be the sun to shine on you and keep you warm.' It poetically describes a willingness to provide support and warmth, symbolized through the imagery of being the 'sun' for someone else, providing necessary sustenance and care unconditionally and reliably.
