Opening line of
张若虚《
春江花月夜》 (Zhang Ruoxu, Tang, late 7th c.), 'Spring River, Flower, Moon, Night', praised by Qing critic
王闿运 as
孤篇压全唐 ('one poem that outweighs all of Tang'):
春江潮水连海平,
海上明月共潮生. The poem weaves moon, river, tide, blossoms, and human separation into one of the most celebrated meditations in classical Chinese verse.
