Public libraries are available throughout the United States, with the Chicago Public Library and the Boston Public Library being the most famous. In downtown Chicago, at the intersection of State St and Congrace Avenue, there is a red building that is known as the Harold Washington Library, the famous public library known to everyone in Chicago. Everyone can access the library during opening hours to read and surf the Internet. Free WI-FI is available. Books are borrowed and need to be “loaned” (local residents can use their own documents). First floor: reception center of the library, audio-visual publication loan office. Second floor: Children's reading room. Other floors, distributed by different categories. Foreign language books, on the seventh floor. Foreign language books here, including Chinese Chinese text books, magazines. From the Washington Library, walk north (Stette Street, north-south through downtown Chicago, parallel to Michigan Avenue) to Macy’s and T J Maxx, the largest retail store in the United States dedicated to discounting prices. Walk north for about 15 minutes to the famous Chicago theater, and walk north for 20 minutes to the Chicago River and see Trump Tower (walking time, all calculated from the library). Traveling to Chicago, if you have more time, rest and read in this library, it is a good choice.
