Opening line of
张若虚《
春江花月夜》 (Zhang Ruoxu, early Tang, c. 700):
春江潮水连海平,
海上明月共潮生 (The spring river's tide rises level with the sea; above the sea, the bright moon is born with the tide). A single-poem masterpiece - Zhang Ruoxu has only two poems extant, but this one is traditionally called
以孤篇压全唐 (a single poem that outweighs the whole Tang).
