唐代大诗人白居易一生写过许多脍炙人口的诗篇。然而,他有一首描写自然景物的诗,却引起了一场“诗案”。他在《大林寺桃花》一诗中说“:人间四月芳菲尽,山寺桃花始盛开。”这一诗句引起了后人纷争不休。有学者认为,既然同是在四月里,已经“芳菲尽”了,怎么又会“始盛开”呢?这不是自相矛盾吗?这件“诗案”也引起了宋代大学者沈括的注意。 The great poet of the Tang Dynasty Bai Juyi wrote many popular poems. However, he has a poem describing the natural scenery, but it caused a “poetry case.” He said in the poem “Da Lin Temple Peach Blossoms”: April Fang Fei in the world, the temple peach blossoms are in full bloom. “ Some scholars think that since the same is in April, has been ”Fang Fei make “, and how will ”blooming " it? This is not self-contradictory? This piece of poetry also caused Song Kuo Shen Kuo’s attention.
