花开半夏伤了流年叶落知秋珍惜时光
[huā kāi bàn xià shāng le liú nián yè luò zhī qiū zhēn xī shí guāng]
Half Summer Bloom Hurts the Passing Years as Fallen Leaves Know Autumn; Cherish Time. It’s about reflecting on time's passing, where summer's bloom fading into autumn symbolizes life changes, advising to cherish every moment.
