在古代,人们习惯称国家监察机关御史台为乌台。典出《汉书·朱博传》“:是时御史府吏舍区井水皆竭;又其府中列柏树,常有野乌千棲宿其上，晨去暮来,号曰朝夕乌。”由此人们就称御史台为乌府或乌署,亦称乌台或柏台。可是,李国文先生在介绍苏轼遭遇“乌台诗案”之祸时,却与众不同? In ancient times, people used to refer to the state supervisory organ Ostai as Wutai. Code of “Han Zhu Zhu Chuan” “: when the imperial government officials are well-quarters wells are depleted; and its Cypriots and cypress trees, often thousands of thousands of places on its shelves, the morning to the evening, the number said North Korea.” This people said that the Oshita station is Wufu or Wudai, also known as Wutai or Parkotherium. However, when Mr. Li Guowen introduced Su Shi’s case of “Wutai Poetry”, he was different.
