你是我的日出
[nĭ shì wŏ de rì chū]
This nickname 'You are my sunrise' represents admiration and dependence on someone, implying he or she can bring hope, light and new power into one's heart just like a bright sun rises slowly from the horizon every morning. In Chinese romantic concepts, using beautiful natural phenomena as metaphors for the other party is a very poetic and affectionate expression way, because natural phenomena can trigger strong emotions and rich imaginations of people.
