Over many years, the Ming family multiplied and grew in the Jiangnan region. After decades and multiple generations of being carefully operated and bold expansions, it finally became one of the leading large families. They eventually made a connection with the Eldest Princess. After they became royal merchants of the palace treasury, the Ming family's reach became longer and deeper through the never-ending stream of silver the palace treasury goods brought in. Not only did they have countless industries in Suzhou and Hangzhou, they directly controlled large amounts of ships, caravans, and stores.
Family members also controlled many business that were unremarkable but deeply connected to the Jiangnan people's lives, such as grain, oil, food, and brothels. So much so, someone once said that as long as Jiangnan people open their door, they will certainly have dealings with the Ming family's industry.
