The different styles of Wang Anshi in his anterior and latter stages of poetic creation have always been attracted attention in academic circles. Some scholars think that Wang Anshi shows the elegance, refinement and great skills in his early poetry works, and his later style is a natural outcome of following the early style. But some scholars think the changes of his later poetry works are associated with his seclusion life and the research on the Buddhist scriptures. However, for his part, when he no longer functions as prime minister, and becomes a recluse, his sense of identity, main literary concern and mentality all have profound change. This leads to the fundamental shift of his later poetical writing in the depth of feeling and the mode of thinking. Although there is an analogy between the early and late poetical writing style, the intrinsic charm of Wang Anshi’s later and early poems can not be mentioned in the same breath, and the outstanding achievement of his later poems cannot be reached only by longterm skills training.
