Woodblock printing is a great invention of the ancient Chinese people after their long-term practice and study. In Sui Dynasty (about 600 A.D.), people got the inspiration from seals and invented the earliest woodblock printing in human history. Woodblock printing has the title of "Living Fossil" in printing history. The origin of woodblock printing in China is Yangzhou, which is the only city in China that keeps a full set of old woodblock printing process. China pays great attention to the protection of intangible cultural heritage. On May 20, 2006, the woodblock printing process was classified in the first batch of State-level Intangible Cultural Heritage List after the approval of China’s State Council. On June 5, 2007, Chen Yishi from Yangzhou of Jiangsu Province was determined by Ministry of Culture as the representative inheritor of the cultural heritage project and was classified in the list including 226 representative inheritors of the first batch of State-level Intangible Cultural Heritage Projects.
