This bank is a financial institution specialized in handling exchange business for Shanxi merchants, also known as "Ticket Village" or "Exchange Village". Because it was founded and operated by Shanxi merchants, it is also called "Shanxi Draft Bank". Shanxi draft bank is the product of the development of domestic and foreign trade at that time, and it is a unique pioneering work of Shanxi merchants who are good at seizing business opportunities. The historical background of Shanxi draft bank originated from the development of commodity economy at that time, the emergence of early financial institutions, accounting firms and banks, and the risk of cash flow of escort agencies.
