入夜渐微凉夭夭桃花凉
[rù yè jiàn wēi liáng yāo yāo táo huā liáng]
Translates to something poetic like 'Coolness sets in at nightfall just as Peach Blossoms wilt coolly'. It uses imagery of nature transitioning, possibly alluding to changes in mood or circumstance as days turn into nights, or youthful vitality fading slowly over time.
