What is Du Mu's literary proposition?

Du Mu is famous for his poetry, prose and calligraphy. In Du Mu's theory of ancient prose creation, the ideology is put in the first place, that is, "meaning", and the momentum of the works is put in the second place, that is, the works are usually said to be smooth and often feel condescending. Some people say that this situation is good, while others disagree. The third place is phrasing, which is obviously a detail. Add a chapter at the end of the article, and there will be a chapter to follow. In ancient times, writing mainly refers to the question of how to write, which is a question of writing skills and layout. In ancient times, it was separate. According to Liu Xie, Wen Xin carves dragons. General skills > > As the saying goes, "This pen has a pen, thinking that those who have no rhyme will write, and those who have rhyme will write". Writing and writing are separated. Writing is almost equivalent to prose, while writing is equivalent to poetry. When talking about his two sons, Yan Yanzhi also talked about a problem of learning from his handwriting and a problem of learning from his pen, which also refers to the difference between rhyming and non-rhyming. According to Du Mu's view, there are poetic prose or prose poems at present, but it is not good for some people, because the articles are "four unlike children", which are both like poems and prose, and it is really unnecessary to stick the separated ones together.
