The rendering of artistic conception refers to relying on scenery and virtual scenery, that is, imagination, to express emotions. There is also a distinction between real objects and virtual scenes. What you see in front of you is real, and what you imagine or appear after traveling through historical time and space is virtual. Only the combination of virtual and real can form a perfect another world.
Only when the artistic conception is integrated with emotions can it have a sense of reality and three-dimensionality. I believe you have the same feeling: when writing a composition, when you encounter something that interests you or has experienced, you will be particularly involved, feel very passionate, and have a lot of thoughts. And when you encounter something you have never experienced before, you will think hard and rack your brains. This is called inspiration and emotion. Put your emotions into writing and you will write perfect poems, and the artistic conception will naturally come out. Of course, the level of artistic conception also depends on many factors such as whether your thoughts are profound.
