Yu Daniang (ä¿Â大å¨Â,"Aunt Yu") was a Chinese businessperson, who lived during the Tang dynasty. During the reign of Emperor Daizong of Tang, she operated a major shipbuilding business, who manufactured and sold boats to the rich and powerful. They were called "Yu Daniang boats" (ä¿Â大å¨Âèªè¹) after her. It was not uncommon for women to manage major businesses at the time. In China, commercial activities had a low status at the time. She is known as one of the most notable businesswomen in China prior to the modern age alongside Widow Qing.
