Three courts and five eyes

China's traditional aesthetics pays special attention to the beauty of human face. There is a saying of "three courts and five eyes" in China's ancient painting theory, which talks about the vertical and horizontal proportional relationship of the positive view of human face.

"Three points" refers to dividing the front face into three equal parts horizontally, that is, one point from hairline to eyebrow line, one point from eyebrow line to the bottom of nose, and one point below the bottom of nose.

"Five eyes" refers to the longitudinal division of the front face into five equal parts, with the length of one eye as an equal part, that is, the distance between the two eyes is the distance of one eye, the distance from the vertical line of the outer corner of the eye to the vertical line of the outer ear hole is the distance of one eye, and the whole front face is divided into the distance of five eyes.

All the faces of the characters drawn according to the proportion of "three courts and five eyes" are very harmonious. The ideal oval face fits this ratio perfectly.
