黄浦江
The bend in the Huangpu River resulted in the formation of an alluvial beach east and south of the bend. This alluvial floodplain was called a "mouth" ("zui") after its shape. It was named after the family of Lu Shen, a 15th-century scholar-official of the Ming Dynasty. Lu's family became one of the most prominent in Ming Dynasty Shanghai, and lived in the Yangjing canal area, east of the Huangpu River and close to today's Lujiazui.
