The second part makes an innovative study of the soul of traditional Chinese graphics in the respect of "shape","essence", and "implication". The first element to be emphasized is "shape", which is mainly concerned with lineal designs and convolute designs in traditional graphics, the main two ethical factors employed in traditional Chinese design. The "shape" is a relatively complete and minute system. What is included in "essence" is to convey the effect of lucency and artistic conception in traditional plastic art, which embodies traditional Chinese philosophy and its aesthetic taste. The "implication" part makes a detailed analysis of the informative function of the particular ethical graphics from the perspective of disseminative theory. The third part is my application of the three elements in designing.
