幻化成蝶却只剩下伤痛旧雨今雨却只剩下回忆
[huàn huà chéng dié què zhĭ shèng xià shāng tòng jiù yŭ jīn yŭ què zhĭ shèng xià huí yì]
Translated to 'Transformed into Butterfly but Left Behind Only Pain, Old Showers and Today's Rain Left Nothing But Memories'. Inspired by Zhuang Zhou's dream where he dreamed he was a butterfly. It conveys feelings of loss and nostalgia, implying beauty and freedom have led only to pain and memory now.
