The Chinatown centered on Grant Avenue and Stockton Street in San Francisco, California, (Chinese: 唐人街; pinyin: tángrénjiē; Jyutping: tong4 jan4 gaai1) is the oldest Chinatown in North America and the largest Chinese community outside Asia. It is the oldest of the four notable Chinatowns in the city. Since its establishment in 1848, it has been highly important and influential in the history and culture of ethnic Chinese immigrants in North America. Chinatown is an enclave that continues to retain its own customs, languages, places of worship, social clubs, and identity. There are two hospitals, numerous parks and squares, a post office, and other infrastructure. Visitors can easily become immersed in a microcosmic Asian world, filled with herbal shops, temples, pagoda roofs and dragon parades.
