This kind of objective feeling is similar to the nature of plane mirror imaging: it is upright and contradicts the conclusion of objects such as large portraits. How is this contradiction formed?

The formation of this contradiction arises from the confusion in our understanding, that is, for the same phenomenon, people from different perspectives use different standards to analyze, measure and judge. Contradictions. As shown in Figure (c)
