In January 2003, Shenzhen established the strategy of a "culture-based city" and the principle of a "cultural economy," aiming to build Shenzhen into a cultural and ecological city of high civilization. While implementing the "culture-based city" strategy, Shenzhen set the goal of building itself into a "Library City," "Piano City," "City of Design" and "Cartoon Animation Base." Now there is a community library for every 15,000 residents in Shenzhen and all the libraries are expected to be E-linked with shared resources. Shenzhen leads the nation in the popularity of piano, with 8.2 pianos for every 100 families. The first China (Shenzhen) International Piano Concerto Competition was held in October 2006 and the competition will now be held every three years. Design has become an important part of residents' lives. During "Creative December" each year, creative design competitions are held among residents and youths.
