Yi Fu, known as the representative poet of confessional school. He told the most familiar and painful details of his life in the form of poetry. His poetic style is straightforward and powerful. Perhaps this writing is out of tune with this era. So, what is a confessor? The so-called confession school is actually the "confession school", which exposes everything hidden in the heart, even selfish, dirty, ugly and despicable things, and tells the most unspeakable side of the heart. At that time, American society was in a turbulent period, and traditional academic poetry was a great constraint on people's creation. Many poets are in a state of nowhere to vent their inner feelings and emotions because of their social environment and creative environment. As a result, various schools of poetry, like hippies in those days, appeared and grew rapidly. After painful reflection, Lowell put all kinds of contradictions reflected in reality and culture in his heart and "frankly confided the loss of personality". Lowell and Boehlmann, two competing confession experts, made confession a peak in Qian Shan. Lowell's poetry seminar at Boston University played an indelible role in promoting Confessions. The appearance of sexton and Plath, the famous poetesss, is like planting a beautiful flag at the peak of the confessional school, announcing the highest achievement of this school's creation.
