Prose often reflects the complex background and profound connotation through occasional and fragmented events in life, so as to achieve the goal of "seeing the world in a grain of sand, and human feelings in half a flower." To achieve this state, conception is the key.
In short, different writers have different methods of planning and constructing a prose, which vary from person to person. You cannot insist on uniformity, let alone imitating cats and tigers. Everyone should have his own unique method, but Paying attention to conception is extremely important for every writer.
