There has always been a dispute between the superior and the inferior in the Tang and Song Dynasties, and the choice of praise and criticism varies from person to person. The strength of Song poetry lies in the improvement of techniques and the expansion of themes compared with Tang poetry. But the more you improve your literary talent, the more you lose your natural voice, and it is inevitable that you will lose your grace and beauty. This is also a helpless move. At the same time, if we blindly seek innovation, change and adventure, we have to pay attention to the use of words, because the use of words damages poetry and meaning. This is where Song poetry is inferior to Tang poetry.
As far as the development of literature is concerned, originality is more important than form, and it is difficult for Song people to continue under the situation that Tang poetry has been in full swing. If you are poor, you will change your mind, so you will expand your territory, set foot in places that the Tang people have never been to, and find another way to form a rival with the Tang poetry. After the Yuan and Ming Dynasties, although poetry also changed, it could not cross the barrier between the two schools.
