Words become sincerity, and people believe what they say. Traditional Chinese culture has always emphasized the importance of keeping promises and keeping promises. Honesty has always been a principle of business in China, and it is also a principle to be upheld in financial activities. Climbing up the stairs, a spacious and bright hall catches the eye. "Northern and Southern merchants" dressed in Republican costumes are trading here... In the exhibition hall of the Shenyang Financial Museum, which was renovated by the former Border Industry Bank, the statues are lifelike and smiling, making people feel as if they have traveled back nearly a century. This is a statue of the Shenyang Financial Museum restoring the business scene of the Border Industry Bank. Qi Xu, the director of Shenyang Financial Museum, introduced that this themed museum building was first built in 1930. Here, visitors not only see the restoration scene, but also understand the origin, development, and evolution of currency. In addition, the museum also houses coins and banknotes from over 210 countries and regions around the world, with rich and colorful content. This is a collection of currencies from around the world in the Shenyang Financial Museum. Passing through the hall, we arrived at the basic exhibition area where the text recorded in the "New Book of Tang: Food and Goods Annals" caught our eyes: "During the reign of Emperor Xianzong, merchants went to the capital and commissioned money and various officials to report to the court and various military and wealthy families, using light clothing to travel to all directions. They combined coupons and took them, known as flying coins." According to Lu Haiying, a researcher at the Shenyang Cultural and Museum Center, flying coins were an early form of exchange business in Chinese history and had already appeared in the mid to late Tang Dynasty, similar to today's bank drafts. ". Compared with the flying money used for foreign exchange in the Tang Dynasty, the special currency of the Southern Song Dynasty, Golden Leaf, which also tells the story of ancient financial integrity, appears quite mysterious. Crossing the 2.5-ton heavy safety gate, 50 year old Guangdong tourist Zhang Juan finally saw the "golden leaves" that great heroes often throw when wandering the rivers and lakes in Jin Yong's novels. She pointed to the "Southern Song Dynasty's One or Two Golden Leaves" engraved with the inscription "Chen Erlang's Very Golden Iron Wire Lane" inside the museum and said, "It turns out that this' leaf 'is not the same as that' leaf '. The' golden leaf 'is not in the shape of a leaf, but in the shape of a book page; the thin gold leaf, folded into several folds, looks like a standing golden book." The picture is "Southern Song Dynasty's One or Two Golden Leaves". Lu Haiying introduced that the name "Chen Erlang" is generally believed to be printed by officials responsible for inspecting the quality of "golden leaves", and there are also names of craftsmen and shops; "Shi Jin" refers to the quality of "golden leaves", which is an important criterion for measuring the value of "golden leaves". Only by determining the quality can it circulate better; "Tiexian Lane" is the place name of Lin'an City in the Southern Song Dynasty, used to inform the specific location of the gold and silver shop. As a type of Chinese deposit and loan currency, "Golden Leaf" has the characteristics of easy portability and easy division, and is very flexible in transactions. It is an important manifestation of the increasing degree of gold monetization during the Southern Song Dynasty. In modern times, the style of currency can better reflect the embryonic form of today's currency. The official bills of the Ministry of Revenue displayed in the museum are decorated with flower, grass, and dragon patterns around them. Above them, there are two columns of "official bills of the Ministry of Revenue" written in both Chinese and Manchu characters. On the left, there is "a certain year, a certain month, and a certain day in Xianfeng", and on the right, there is the number (equivalent to the printing number of today's banknotes). The denomination is stamped with Han and Manchu characters. The Qing Dynasty banknotes, on the other hand, are closer to modern banknotes, with the bill number and face value written in the center. This is the Qing Dynasty banknote. Wang Li, a researcher at the Shenyang Financial Museum, said that these two treasures
