Jewelry Market Street is the most concentrated area of furnace shops in Qing Dynasty, forming a money market. After the Republic of China, the furnace shop was depressed and there was no market in the money market, so it was changed into a silver shop, forming a narrow lane. There are four groups of three-way houses and a sidewalk in the south of the street. Each group of three-way houses covers an area of 80 square meters. Judging from the signs of changes in the plaque on the door, it was a stove shop at that time and later changed to a shop workshop. Street North Group 4 is a single-family house with two or three floors, which used to be a bank.
The structure of Sanheyuan adopts China traditional wood structure, brick gatehouse, beam roof truss and upturned tile roof. The roof is also a louver window, which is the workshop for smelting silver ingots in the furnace. The architecture in the north combines Chinese and western styles, and the decorations such as bolt, window cover, cornice foot and iron flower guardrail all reflect the combination of Chinese and western styles. The second half of the three-story building is Chinese architecture, and the first half has a pavilion with two slopes as a transition between Chinese and western styles. There is a stone plaque on the door, which is called "Datong Bank". On the second floor, there is a stone tablet on the door that says "Bank of Feng Wan". At the western end of the hutong are two rows of bungalows, with a raised yard in the middle and suspended gable roofs and skylights on both sides. Qianshi Hutong is the earliest and most complete financial exchange in China. At the same time, creating a compact and diverse architectural space environment on a narrow land not only embodies the unique attributes of this street, but also shows the ingenuity of architects.
On both sides of Qianshi Hutong in Qing Dynasty, there were workshops specially approved by the government at that time, specializing in precious metal smelting and casting industry, which was called "furnace line" at that time. The Qing Dynasty's Collection of Notes and Stones records: "In Yin Qian, the middle part of the jewelry market outside Qianmen, and the west alley." Before the end of the Qing Dynasty, banks, grain depots and large firms from all walks of life in Beijing went to the money market every morning to exchange money for money or money for silver, so the money market became an important financial market at that time. After the founding of the Republic of China, the kiln company lost the franchise granted by the government. Coupled with the currency reform, the demand for precious metal casting market has shrunk, and the melting furnace company has been depressed and transformed into a bank store. Therefore, it can be regarded as the earliest and most complete financial exchange in China. At that time, banks on both sides of the top ten hutongs exploited the loopholes of the law, expanded their business buildings without restraint, and embezzled public access, eventually making the top ten hutongs the narrowest hutongs in Beijing.
