It can be said that the Money Exchange was built at the strong request of the aristocratic families and wealthy merchants clinging to Chen Xi's support. However, to fully cover all regions, Chen Xi needed help from these families and merchants, as they all had a complete network of relationships in their areas, which also served as the prototype of the aristocratic family's network.
