Districts of Shanghai in the context of Jing'an District

The Shanghainese language, also known as the Shanghai dialect, or Hu language, is a variety of Wu Chinese spoken in the central districts of the city of Shanghai and its surrounding areas. It is classified as part of the Sino-Tibetan language family. Shanghainese, like the rest of the Wu language group, is mutually unintelligible with other varieties of Chinese, such as Mandarin.

Shanghainese belongs to a separate group of the Taihu Wu subgroup. With nearly 14 million speakers, Shanghainese is also the largest single form of Wu Chinese. Since the late 19th century, it has served as the lingua franca of the entire Yangtze River Delta region, but in recent decades its status has declined relative to Mandarin, which most Shanghainese speakers can also speak.

Yangpu (Chinese: 杨浦区) is one of the 16 districts of Shanghai. It is located in the northeastern part of downtown Shanghai, bordering the Huangpu River on the east and south, Hongkou on the west, and Baoshan on the north. The southern part of Yangpu District is 4 km (2.5 mi) away from The Bund, a major tourist attraction. It is predominantly composed of residential communities, with a total area of 60.61 km (23.40 sq mi) and a population of 1,242,548 as of 2020. The district administers 12 subdistricts.

Songjiang is a suburban district (formerly a county) of Shanghai. It has a land area of 605.64 km (233.84 sq mi) and a population of 1,909,713 (2020). Owing to a long history, Songjiang is known as the cultural root of Shanghai.

Songjiang Town, the urban center of the district, was formerly the major city in the area. It is now connected to downtown Shanghai by Line 9 of the Shanghai Metro.
