你是我的小小太阳你是我的大大月亮
[nĭ shì wŏ de xiăo xiăo tài yáng nĭ shì wŏ de dà dà yuè liàng]
"You Are My Little Sun And My Big Moon" is affectionate and poetic. This name uses celestial bodies to symbolize importance, love, and care in relation to another person, expressing deep emotional reliance and affection similar to how day relies on sun and night relies on moon.
