Symmetry is the main characteristic of Chinese style in design language, which is an embodiment of the Doctrine of Mean and the idea of degree in form, which on the one hand represents the central feeling of a powerful country, i.e. the embodiment of center of symmetry, on the other hand represents the impartial attitude in their handling of affairs. So, most of the Chinese traditional graphic design or product design systems embody the central symmetry, axial symmetry and the symmetry of the center of gravity.
