2. Li Shangyin was a poet with unique achievements in the Tang Dynasty, which had a great influence on later generations, but his evaluation was quite different. His modern poems, especially the Seven Rhymes, are unique in style, beautiful in words, and ethereal in artistic conception, which has made great contributions to the development of poetic art forms. Some of his poems directly express his attitude towards current affairs and politics, some satirize the past and praise historical themes, some express friends' feelings of life and death, and some are sentimental. However, people are most familiar with his love poems.
