天若有情天亦老动我姐妹死得早
[tiān ruò yŏu qíng tiān yì lăo dòng wŏ jiĕ mèi sĭ dé zăo]
This name is a mix of classic poetry and colloquial slang. 'If heaven has feelings, even heaven will grow old' is a quote implying that strong emotions can affect even celestial bodies. The latter part 'If you mess with my sister, you'll die young' uses humor to express protective feelings for one's sister or close friend.
