How to treat the disappearance of old crafts

Old craft is an important part of supporting Chinese Millennium civilization. Their aging, just as the Four Books and Five Classics become the embellishment of education rather than the mainstream, is sad, but it is only the necessity of civilization upgrading. How many people's memories can be reliable after years of washing? "The solitary sail is sailing in the sky, and only the Yangtze River flows in the sky." When the decline of the old craft is irreversible and the inheritance is unpredictable, use a real image to enrich the imagination of future generations to their ancestors.
