Traditional gold and copper handicrafts use techniques such as engraving, inlaying, and inlaying gold and silver on copper crafts. Special chisels are used throughout the operation of traditional gold and copper handicrafts, and the operator's skills must be exquisite and mature. This craft has a long history, rich cultural heritage, and profound historical and cultural significance. It is a handicraft with Chinese characteristics. Chengdu is a cultural treasure house with a long history. According to historical records, the King of Shu moved his capital here as early as the early Warring States Period, and the city has a history of more than 2,300 years. Its cultural accumulation has reached more than 4,000 years, which can be said to be a place of great wealth and outstanding people. In the Sanxingdui and Jinsha cultural eras, the bronze casting industry here was already very developed. While the bronze casting industry was developing, it also promoted the development of gold and copper handicrafts. At the end of the week, the ninth generation of the Shu King Kaiming moved from Pi County to Chengdu. "In one year, the place where he lived became a gathering, in two years it became a town, and in three years it became Chengdu." The name "Chengdu" came from this. Chengdu Yangzi Mountain earth platform, the "stilted" house ruins of Twelve Bridges, the ship coffin ruins of the commercial street and the Jinsha ruins prove that the center of the ancient Shu people's activities was in Chengdu. Dujiangyan City is located on the northwest edge of the Sichuan Plain in the central part of Sichuan Province, between 30443122 north latitude and 1032510347 east longitude. The city has a population of about 650,000, 48 kilometers southeast of Chengdu City, bordering Pi County to the east, Wenjiang and Chongzhou to the south, Wenchuan County of Aba Prefecture to the west, and Pengzhou City to the north. The northwest of the city is mountainous and the southeast is a plain area. Because of the world cultural heritage Dujiangyan, the territory is densely covered with water networks, convenient irrigation, and rich cultural heritage. In the Tang and Song Dynasties, it was a distribution center for inland materials on the Ancient Tea Horse Road, with a developed history and culture and prosperous trade. Due to the special economic and geographical location of Dujiangyan in southwest China, it has become an important political and military stronghold in history, and the local economy is also very developed. As people's living standards improve, the demand for handicrafts increases, which also provides a good development space for the rise and development of related gold and copper handicrafts such as engraving, inlaying gold and silver, inlaying, gilding, and gold and silver flat supports. Chengdu Jinglu Sculpture Art Institute has continued the traditional handicraft production methods, and continues to retain the way of master-apprentice, oral and practical teaching, and hand-in-hand teaching. The exquisite copper handicrafts produced have high collection value and inheritance value. Now, the damaged unearthed cultural relics and national-level copper handicrafts can be repaired using ancient methods, and this technology can be used to replicate precious cultural relics, providing more technical support for the protection of cultural relics.
