念着旧情
[niàn zhe jiù qíng]
'Nianzhejiuqing' means 'missing the old love' in Chinese. It conveys that the person who holds this nickname probably has an unbreakable attachment to his or her former partner, a certain period of past life, things in the past, etc. The Chinese people prefer to be emotional and express feelings implicitly, so this name sounds poetic and romantic.
