Huasi xiangqian is a traditional metalwork craft, often called filigree inlay. Gold or silver is drawn into fine wire, which is then twisted, piled and woven into patterns, and gemstones are set into the finished piece. It belongs to the 'eight wonders of Yanjing', Beijing's traditional crafts, and was added to China's national intangible cultural heritage list in 2008. Palace jewellery was one of its classic uses. Where the Mask Ends is reported to use filigree and chasing in its costumes' jewellery.
