乌衣巷口夕阳斜清风街头火流萤
[wū yī xiàng kŏu xī yáng xié qīng fēng jiē tóu huŏ liú yíng]
This vivid phrase can be interpreted as 'Fireflies Flare at the Streets of Qingfeng on Twilight Slanting Across Wuyi Alley Mouth.' It evokes a nostalgic image from classic Chinese culture, referring to an ancient alley with a long history where once bustling activities are now almost gone. Fireflies flying under the evening breeze suggest fleeting time and beautiful yet sad changes.
