1. Curves and radians of arched doors or arched elements can weaken the sharpness of corners and soften the visual effect of space. The upper part of the arched door is arched in an arc, which gives people the feeling of stretching upwards and can visually enhance the height of the space.

2. Enhancing the artistic sense of arc, curve and parabola in space itself has a high artistic temperament and aesthetic feeling, which can strengthen the artistic atmosphere of space and beautify the horizontal and vertical single space structure, which not only enhances the value but also highlights the connotation.

3. Separate the space and enhance privacy. The use of arches can divide the space into independent areas, which not only ensures the privacy of the space, but also does not make the space appear abrupt.
