As a conical section, the ellipse has two focal points from the beginning, which makes it different from other geometric figures. Mathematicians have found that any straight line passing through the center point of an ellipse can cut the ellipse into two identical figures. Because of the symmetry and balance characteristics of the ellipse, compared with other geometric figures, it looks more complete and full as a whole. The slightly expanding outward curve contour has dynamic tension in the static state, which is very easy to create an intriguing Visual thinking space. Inspired by the ellipse, Japanese Taiping Zhengfang summed up the ‘ellipse philosophy’ in the economic field and tried to find a balance between the two focal points in the complex economic relationship. Today, Japan is still developing rapidly in the direction he envisioned.
