Chinatown is located in Chicago's South Side in the Armour Square neighborhood between Cermak Rd and Wentworth Ave. The document discusses the history and demographics of Armour Square, describing how it was settled in the late 19th century and became home to Chinatown in the early 20th century as the Chinese population faced discrimination elsewhere. It also recounts the group's visit to Chinatown Square and other landmarks, and reflects on the authentic experience of exploring this area of Chicago.
