In Chinese, the urban centre of a city is called the "city centre" or "urban core" (Chinese: 市中心; pinyin: shì zhōngxīn). In many cities, it is the historical city centre and the cultural and commercial centre. Historically, the CBD often occupied one portion of the city centre. In recent years, larger cities have often developed CBDs or financial districts that occupy a part of the city centre or are outside the historical city centre completely. For example, Beijing's historical city centre is defined by the former city walls and remains the political and cultural centre of the city, but Beijing's CBD sits in Chaoyang District, to the east of the historical city; Shanghai's city centre was defined by the Old Chinese City, the International Settlement and the French Concession and sat on the west bank of the Huangpu River, whereas the modern financial district is concentrated on Lujiazui, a newly developed area across the river from the traditional city centre (although parts of the traditional city centre remain key financial and business centres).
