How to understand that the form is scattered but the spirit is not scattered?

"Form is scattered but spirit is not scattered" shows the external and internal aesthetic characteristics of prose, and the dialectical relationship between "form" and "spirit" makes prose have unique charm and charm. The "spirit" of prose should not be scattered, but should be transformed into the "shape" of "scattered"; The "form" of prose should be "scattered", but it should be integrated with "spirit", which is the aesthetic connotation that distinguishes prose from all other styles. So, how to unify the "form" and "spirit" of prose? Qin Mu, a famous essayist, once made a very vivid metaphor in On Prose Creation: "Although prose is scattered but not chaotic, all materials are unified by thought, and the pearls of life are strung together with a thread of thought, so that the pearls will not roll around. This is a neat string of beads." For example, "Autumn in the Old Capital", because the author pursues "purity" and "quietness" and is shrouded in faint sadness, he does not write about the warm red leaves of Xiangshan or the Summer Palace where tourists are woven. The author is "renting a house", "seeing a high blue sky" and "counting a little bit of sunshine".
