In recent years, the stories of Jin merchants have been frequently put on the TV screen, such as 02 "Go to the West Exit", "Qiao's Courtyard", "Silver Empire", etc., all of which tell the arduous process of the development of Jin merchants. What is less known is that the Jin merchants in the late Ming Dynasty played a very disgraceful role in history.

At the beginning of the establishment of the 02020202 Ming Dynasty, in order to prevent the harassment of the remnants of the Mongol forces, Zhu Yuanzhang set up nine military towns along the Great Wall, each of which provided its own granary, two of which were located in Shanxi. In order to ensure the supply of military rations, the government encouraged private individuals to transport grain to the granaries of military towns, and after receiving the grain, they issued 02 "salt guides" (vouchers for the sale of salt) to merchants who trafficked salt.

02020202 later, the government directly changed the "salt introduction" to silver, and many Jin merchants began to engage in selling grain in Tuntian in exchange for silver, and soon amassed huge wealth.

02020202 Jin merchants are expanding in size day by day, and they need a larger market. A large number of Jin merchants began to look for new partners, and Houjin in the Northeast was their best choice.

In the 46th year of Wanli 02020202 Ming Dynasty, Nurhachi promulgated the "Seven Great Hatreds" as a political declaration of the Later Jin Dynasty and the Ming Dynasty, and this declaration was brought back to Guannai through the Jin merchants to distribute. When Nurhachi captured Fushun, he rewarded 16 local Jin merchants. In order to achieve the goal of Dingding Central Plains, Nurhachi borrowed money from Jin merchants and offered high interest returns. In this way, the military expenditure required for the expansion of the Houjin will be easily solved. After Huang Taiji ascended the throne, he tried his best to win over the Jin merchants, adopted various preferential policies to attract them to the northeast to do business, used their greedy nature to reserve military strategic materials for the Houjin, and actively developed some people to spy on the military and economic intelligence of the Ming Dynasty.

02020202 with the help of the Jin merchants, Houjin prepared enough grain and grass, built a well-equipped Eight Banners iron armor, and obtained a large amount of military and economic information of the Ming Dynasty. After the Qing army entered the customs, in order to thank the Jin merchants for their contributions, the Shunzhi Emperor personally met with the eight Jin merchants, and crowned them as "imperial merchants", and gave them all the right to operate the northern border trade, and other private individuals were not allowed to touch it without authorization.
