The origin of Huize copper coin

Datong Coin is located in Huize Park, No.366 Bao Tong Road, Huize County, Qujing City, Yunnan Province. The sculpture of ancient coins with a diameter of 22.6 meters and a weight of 77,777 kilograms was creatively designed by Professor Xie Bingman, an internationally renowned architect. It is the best in the world. Magnified by 39 times, the sculpture of ancient coins stands on the central axis of the city. A colorful "Rainbow Bridge" spans the water, and the bridge is light and transparent. From being in a "line hole" in time tunnel, standing between heaven and earth, overlooking the past and present, and running through the future, it symbolizes the glorious history of Huize copper industry and reminds people of the prosperous times when one mountain is full of treasures and four fields are filled with smoke.

Two climaxes of Huize copper merchant culture. According to the isotopic archaeological research of Mr. Jin and Mr. Li Xiaocen, the earliest appearance of Huize copper can be traced back to the late Zhou Dynasty 3,200 years ago. During the period of 100 from the middle of the 2nd century, Huize copper merchant culture ushered in its first climax. According to archaeological findings, Tang Lang bronze washing utensils (copper pots, pots, pots, drums and other household utensils) produced by Huize have been unearthed in Zhaotong, Yunnan, Mianxian, Shaanxi and other places, indicating that the utensils produced by Huize have enjoyed a high reputation and are exported to the whole country, which has affected people's lives to a certain extent. In the era of difficult transportation and logistics, the widespread spread of copper washing shows that the embryonic form of copper merchant culture has been formed at that time. Ming and Qing dynasties to modern times is the second climax of Huize copper merchant culture. Especially in the nearly 200 years from the 21st year of Kangxi (1682) to the 6th year of Xianfeng (1856), Huize copper mining industry gradually flourished, including mining, smelting, purchasing from other provinces, casting drums in this province, and transportation in Beijing. People coming and going from Huize are in an endless stream, gathering in large numbers and imposing. This is also considered to be the real formation period of Huize copper merchant culture.

The main content of Huize copper merchant culture. The material basis of Huize copper merchant culture includes the exploration, mining and smelting of copper, the drum casting of copper coins, the outward transportation of copper and the development of copper art, such as copper smelting. According to statistics, from 1705 to 1806, there were more than 30/44 copper factories in Yunnan Province, including the thirty-seventh year of Kangxi. Most of these copper plants are smelted in local smelters, with the highest annual output exceeding10 million Jin. Another example is the drum casting of copper coins. The drum casting of Huize copper coins began in the 12th year of Qing Yongzheng (1734) and lasted for more than 200 years. There are two new and old "Baoyun" mint bureaus, which are the second largest mint bureaus in China after Beijing Baoyuan and Baoquan. The outward transportation of copper has formed a magnificent landscape of copper transportation from Wan Li to Beijing.

Huize copper art is even more dazzling. Tanglang Copper Wash, which originated in the middle of the Western Han Dynasty and flourished in the Eastern Han Dynasty, inherited and developed the thin-walled casting technology. Its distinctive feature is that the abdomen has strings and the bottom has patterns and inscriptions. Its popularity in the whole country led the aesthetic and fashion trend of that era to a certain extent. According to "Huayang Guozhi Nanzhongzhi" in the Eastern Jin Dynasty, "Tanglang County is also famous for its mountains. Silver, lead, copper, miscellaneous drugs. There is Tanglang Aconitum. " This is the earliest record of white copper production in human history, which is earlier than Europe 1500 years, indicating that Huize copper art had developed to a quite high level at that time. The "Jiajing Bao Tong" commemorative coin minted by Dongchuanfu Coin Bureau in Ming Dynasty is the largest and heaviest ancient metal coin ever found in the world and the largest coin recorded in Guinness Book of Records, so Huize is called the land of rich kings. The art of spot copper, which originated in the Ming Dynasty, is the only metal object in the world that can be forged without smelting, and is known as a must in China. In addition, there are techniques such as "floating furnace" and "removing silver from black copper", which have witnessed the richness and long history of Huize copper art.
