One of the most important tenets of Chinese art is continuity. A painter or potter is highly respected if he could copy the works of his master to such extraordinary likeness that one cannot differentiate his work from that of his master’s when placed side by side. Likewise, his master would win praises for his generosity in imparting his knowledge and skills to his disciples to such a degree that not only his disciple is now at par with him in terms of skill and creativity, continuity is assured even when he is no longer capable. From there, the disciples would be encouraged to develop styles of their own under the watchful eye of the master and that is how Chinese art sustains and evolve. With duplicates around. And only those with training, experience and a keen eye can differentiate the copies from it’s original.
