The Ming family helped the Second Prince and Eldest Princess carry out the palace treasury's plan to smuggle property. The representative of the Ming family was Old Master Ming Qingda. He was the leader of the entire Jiangnan business. The Ming family thrived in the Jiangnan area, controlling a large number of ships, car dealers, and shops, as well as businesses that were closely related to the Jiangnan people.
