Abstract: Du Fu's poems featured a very broad range, which is the expression of the Great Tang Dynsaty. Du not only established his own poetic theory but also put it into practice. As a productive poet of the Song Dynasty, Su Shi extended and developed Du's poetic theory and created his own. Su's poems featured a close connection of article-ology and a broader range of varieties. Written in a period which was called the Oriental Renaissance, there was much comparability between the poems of Du, Su and those of Christina Rossetti. From the comparison, the motivation of Su's ordinariness is discovered: the inclusiveness of his religious vie.
