What are the studies on Li Shangyin's poems in history?

Li Shangyin is undoubtedly one of the most poetic poets in the history of China's poetry. Since the new era, Li Shangyin's research has also achieved fruitful results. According to statistics, over the past 20 years, more than 40 monographs on Li Shangyin's research have been published in the mainland, and excellent works have appeared in all aspects, and a large number of research papers have been published every year. Moreover, since the establishment of 1992, Li Shangyin Research Association has done a lot of work under the guidance of successive presidents such as Wang Meng, Liu Xueyan and Dong Naibin. Zhang pointed out that the higher education version of China Literature History "changed the writing style of previous literature history, and devoted a chapter to Li Shangyin, which means that Li Shangyin's position in the history of poetry has entered the ranks of everyone represented by Li Bai, Du Fu and Han Yu, which is an important symbol of Li Shangyin's enthusiasm in the new era and a breakthrough in Li Shangyin's research." (Breakthrough and Expectation of Li Shangyin's Research in the New Period, China's Poetics Research and Li Shangyin's Research Album). This is known to most researchers.

It should be said that Qi Xin, a researcher, finally let Li Shangyin walk out of the dust of history and glow with his most unique poetic light. Since the new period, the research on Li Shangyin has not only achieved many achievements, but also is very comprehensive and neat compared with other poets in the Tang Dynasty. Tao pointed out that as far as the study of Tang poetry art is concerned, since the new period, "Li Shangyin's research has gained the most" (Current Situation and Thinking of Tang Poetry Art Research, Yearbook of Tang Literature Research 1999), and there is nothing wrong with transferring this language to evaluate the whole study of Li Shangyin.

Wu Diaogong's On the Hazy Beauty of Li Shangyin's Poems holds that Li Shangyin's poems are "interesting in irregular changes", "interesting in disordered words without artistic conception" and "interesting in proximity but not floating, far and inexhaustible", thus forming the aesthetic characteristics of hazy beauty. Chapter VII "Artistic Features of Li Shangyin's Poetry" Liu and Yu Shucheng believe that Li Shangyin's poetry "has the characteristics of profound sustenance, meticulous conception, implicit artistic conception, beautiful charm, beautiful language, sonorous rhythm and ingenious allusion, which shows his unique artistic style of profound elegance and rich symbolic implication."

Another example is Li Shangyin's Poems collected by Liu Xueyan and Yu Shucheng. This book is a collation, annotation, evaluation and annotation of Li Shangyin's poems, and a comprehensive summary of the previous research results, which is of great significance.
