The filigree inlay production technique is an excellent traditional production technique in my country. The filigree inlay in Beijing first appeared in the late Shang Dynasty, and has a history and cultural heritage of more than 3,000 years. Since the Yuan, Ming and Qing Dynasties, the court has set up the Ministry of Industry, the Ministry of Imperial Household Supervision and the Imperial Household Department, and summoned skilled craftsmen from all over the country to Beijing, so that the filigree inlay production technique has integrated the strengths of various nationalities and schools, and has become an important part of Chinese royal crafts and court art. After the founding of New China, the Beijing Municipal Government took emergency measures to rescue the filigree inlay industry and resume production. It awarded Bi Shangbin, Zhai Deshou and Zhang Guanghe the title of "old artist" and encouraged them to take apprentices. Wang Shuwen and Cheng Shumei are representative figures in the second generation of filigree inlay industry in New China cultivated by these "old artists". The emergence of these new inheritors has brought the filigree inlay craft to another period of prosperity. The filigree inlay production technique in Beijing is exquisite, the shape is diverse, and the glaze is pure and bright, reflecting the aesthetic taste of the royal family. It has breathtaking and priceless artistic value, academic value and economic value. The filigree inlay technique is also known as "fine gold craft", which is actually a combination of "filigree" and "inlay" techniques. Filigree uses gold, silver and copper as raw materials, and adopts traditional techniques such as pinching, filling, accumulating, welding, weaving and stacking. Inlay uses techniques such as filing, chiseling, hammering, stuffing, beating, collapsing, squeezing and inlaying to make metal sheets into trays and claw-shaped grooves, and then inlays them with pearls and gems. Beijing filigree inlay is a barometer of our country's cultural and artistic aspects and handicraft standards. It is gorgeous yet solemn, eye-catching yet stable, and lifelike, and behind it is an artistic classic and the foundation of culture. As the "historical business card" of Beijing, it is a vivid textbook of Chinese traditional culture both in art and in academia. At present, there are two representative inheritors of filigree inlay craftsmanship in Changping: one is Yuan Changjun from Beijing Boyiyuan Arts and Crafts Co., Ltd. in Changping Town, Changping District, and the other is Liu Dejun from Beijing Delong Yujie Trading Company in Gaoyakou, Liucun Town, Changping District, Beijing. Both inheritors are disciples of Mr. Wang Shuwen, a Chinese arts and crafts master and national-level inheritor of filigree inlay craftsmanship.
