古城里长桥上人未散夜未央
[gŭ chéng lĭ zhăng qiáo shàng rén wèi sàn yè wèi yāng]
Translated to 'People have not dispersed on the long bridge of the ancient city at night', it creates a picture of people lingering in an ancient place under the sky, expressing nostalgia for time and sentimentality about life that hasn't ended yet. 'Night has not passed' ('night not central') is used here as a poetic way to imply it’s still early night.
