Which city in China is known for its historical international concessions and various cultural influences?

Shanghai is the city in China recognized for its historical international concessions and diverse cultural influences. During the 19th and early 20th centuries, Shanghai served as a major international port and financial center, attracting foreign merchants and diplomats. This led to the establishment of various foreign concessions, where different countries exerted control and influence, resulting in a unique blend of architectural styles, cultural practices, and social structures. The city embodies a mix of Eastern and Western cultures, visible in its cosmopolitan atmosphere, cuisine, and arts.

Beijing, as the capital of China, holds significant historical and political importance, primarily connected to imperial history rather than international concessions. Tianjin, while also featuring some foreign concessions, does not match Shanghai's extensive history and cosmopolitan character. Hong Kong, although known for its colonial past and diverse influences, was not officially a part of mainland China until 1997 and has a distinctly different status and narrative compared to cities on the mainland. Thus, Shanghai stands out as the prime example in this context.
