Origin and Story of 一知半解

During the Song Dynasty, the poet Chen Shidao believed that Su Dongpo's poetic style initially imitated Liu Yuxi and later learned from Li Bai.

However, the Qing Dynasty work "Shichun" (Essence of Poetry) held a different view: "Indeed, his poetry stands alone through the ages, not merely the work of one generation or one person. For Chen Shidao to claim that he first learned from Liu Yuxi and later from Li Taibai (Li Bai), wasn't that merely a superficial understanding (一知半解)?"
