The Chinese Culture Center of San Francisco endeavors to elevate the arts and culture of one of America's first Chinatowns, which is also one of the largest Chinese communities outside of Asia. Since 1973, the CCC has hosted 100 exhibitions, and 33,000 visitors engaged in their programs in 2010 alone. A two-hour Chinatown Heritage Walking Tour guides visitors through the narrow, winding streets of the city's vibrant Chinatown, stopping at temples, herb and tea shops, architectural and historical sites, and the occasional red octagon. Titled "A Tale of Two Chinatowns," this tour provides history behind a variety of sites and discusses the evolution of Chinatown's culture. Most tours will visit the salient sites of Portsmouth Square, Tin How Temple, the Chinese produce markets, and the fortune cookie factory.
