天亮你是小太阳天黑你是小星星
[tiān liàng nĭ shì xiăo tài yáng tiān hēi nĭ shì xiăo xīng xīng]
Translating to 'In the Daytime You're the Little Sun, At Night You're the Little Star,' it portrays admiration for someone important and beloved by the creator. They feel this person shines brightly like the sun during the day and twinkles brilliantly like a star during the night.
