Filament mosaic technology had its embryonic form as early as the Spring and Autumn Period, and the dislocation of gold and silver in the Warring States Period and the leveling of gold and silver in the Tang Dynasty were its predecessors. At present, the tang dynasty bronze mirror Feather Man, Flying Phoenix and Hua Niaowen's Gold and Silver Flat Back in Beijing Chinese History Museum are its representatives. During the Yuan, Ming and Qing Dynasties, the largest filigree production center in China was formed in Beijing. The Ming dynasty reached a superb artistic level, and the Qing dynasty made greater development. Famous products are constantly emerging, and many of them have become court tributes.

Filament inlay is a traditional court art, and its process is complicated and tedious. The basic techniques of wire inlay can be summarized in eight words: kneading, filling, stacking, laying, weaving, braiding, storing and welding. These eight techniques can be matched in turn according to the actual situation in the specific operation process. Mosaic technology mainly depends on filigree technology, or filigree technology also highlights mosaic technology. From the mosaic technology of Beijing filigree in Ming and Qing Dynasties, the mosaic technology can be divided into filing, painting, collapsing, squeezing and embedding.

It has exquisite skills, beautiful shapes, various varieties, obvious China characteristics and national style, and embodies the wisdom and artistic creativity of the Han nationality. Because the court has established handicraft workshops and factories, skilled craftsmen from all over the country have been concentrated, so that the filigree mosaic skills between the north and the south can be exchanged, and the advantages of ethnic arts and crafts have been integrated, which has become an important part of the court art. The representative works of filigree mosaic include the golden crown of Emperor Wanli in Ming Dynasty, the Gu Yong Cup of Jin 'ou in Qing Dynasty, the bonsai of golden peach trees in a silver hexagonal basin, the crown with gold jewelry, the modern Hall of Praying for the New Year in the Temple of Heaven and the Chinese Century Dragon.
