1. Wang Anshi said about Zhang's poem: "It seems the most extraordinary, but it is actually easy to realize." The "extraordinary rise" in Wang Anshi's novels is characterized by thinness and strength, which is an artistic realm pursued by Wang Anshi, but it is regarded as the normal state after entering old age. That is, it is tragic in leisure, fresh and leisurely, gloomy and tragic, which is called "Mid-Levels Poetry". Mid-levels is the place where Wang Anshi lived in Jiangning in his later years. His poems in this period were transcribed into Mid-Levels Collection, also known as Mid-Levels Poetry, and the main genre was quatrains.

2. "Wang Ti" means "Mid-Levels Poetry" or "Mid-Levels Poetry", which generally refers to Wang Anshi's poetry creation in his later years. It is characterized by re-refining meaning. For example, "Climbing to the Top" shows the poet's foresight and boldness of vision by writing about climbing the mountain tower. It also emphasizes rhetoric, such as "boating in Guazhou", as well as using things, coining words and refining words. The main carrier is his elegant quatrains in his later years. The strength of Wang Ti lies in its skillful writing, practical and accurate antithesis. It is both profound and unpretentious, and it is also the pioneer of Jiangxi School.
