你是太阳会发光我是镜子会反光
[nĭ shì tài yáng huì fā guāng wŏ shì jìng zi huì făn guāng]
The comparison between sun (which shines) and a mirror (that reflects shine) illustrates how one sees another person as their source of light and happiness while they reflect that light but can't generate their own. It shows dependency and admiration toward someone.
