Poetry has been in decline since the Song Dynasty. The main problem is the lack of innovation. No matter in terms of content, subject matter, artistic style or genre, it cannot break away from the stereotypes of the predecessors. Many writers simply imitate the ancient times. For the purpose, even the original and innovative spirit of the Song people was lost. However, the number of works of these generations is quite astonishing. There are more than 4,000 poets recorded in "Chronicles of Ming Poems" alone, almost twice as many as in "Complete Poems of the Tang Dynasty". Therefore, excellent writers' works are still emerging.
