During the 19th century, the lower portion of Mott Street south of Canal Street was part of the Five Points, a notorious slum neighborhood in lower Manhattan. In 1872, Wo Kee, a Chinese merchant, opened a general store on Mott Street near Pell Street. In the years to follow, Chinese immigrants would carve out an enclave around the intersection of Mott, Doyer, and Pell Streets. At the time, it was mostly Cantonese males who immigrated, and what was to become Chinatown first began as a very small Bachelor's Society. Most of these immigrants were from Taishan, in southwestern Guangdong, China, so as a result it was first a Taishanese community. That all changed during the 1960s, when an influx of Cantonese immigrants from Hong Kong and Taiwan began arriving, as well. As a result, Chinatown began expanding quickly, and Standard Cantonese, which is spoken in Guangzhou, China and in Hong Kong, became the dominant language of the neighborhood. At the time, Chinatown was emerging and growing as a "Little Hong Kong", but the growth slowed down later on. Manhattan's Chinatown has since grown into the largest Chinatown in the United States, engulfing a large swath of the Lower East Side. Nevertheless, the historic heart of Chinatown, as well as the primary destination for tourists, is still Mott Street between Canal Street and Chatham Square. This is center of what is known as the Old Chinatown of Manhattan.
