It's nonsense to shoot the midline of the panorama.

By querying the information of hummingbirds. We know that the center line of panorama is an invisible line connecting the lens and the subject when shooting, and it is the basis of all composition.

This line is empty and needs the photographer's imagination. Taking the subject as the origin, the photographer's position will change constantly, and so will this line. Photographers need to judge according to different situations.
