Yu Guangzhong is a complicated and changeable poet, and his changing track can basically be said to be a trend of the whole poetry circle in Taiwan Province in the past 30 years, that is, westernization first and then regression. In the early poetry debates in Taiwan Province and the rural literature debates in the mid-1970s, Yu Guangzhong's poetry theory and creation showed a strong tendency of advocating westernization, ignoring readers and being divorced from reality. As he himself said, "When I was a teenager, my pen was touched by the aftermath of Heaton Ling Ke, or the river of the Thames. The brewing industry is nothing more than 1842 wine. " After the 1980s, he began to realize the importance of his country to his creation. He extended his poetic pen back to that continent and wrote many homesick poems. His attitude towards local literature changed from opposition to kindness, showing an obvious trajectory of returning from west to east, so he was called a "prodigal son" by Taiwan Province provincial poetry circles. From the perspective of poetic art, Yu Guangzhong is an "artistic hybrid poet". His works are extremely inconsistent in style. Generally speaking, his poetic style varies from subject to subject. Poems expressing will and ideals are generally magnificent and powerful, while works describing homesickness and love are generally delicate and soft.
