Opera helmets are a general term for various crowns and hats worn by characters in traditional Chinese operas. Their production techniques have a long history, dating back hundreds of years. The main processes include painting, carving, chiseling, dyeing, velvet wrapping, filigree, and assembling. Opera helmets are a product of the development of drama. They focus on decorativeness and are often decorated with pearl flowers, pompoms, silk ribbons, pheasant tails, etc., which are coordinated with the costumes worn by opera actors to enrich the image characteristics of drama characters. Opera helmets are divided into turban hats and helmet hats, also known as soft hats and hard hats. Turban hats are made of fabrics such as silk and satin with embroidery techniques and have a soft texture. The helmets are first made of cardboard into hat blanks, decorated with patterns such as dragons, phoenixes, lions, and tigers, and then assembled with pompoms, beads, etc. On May 24, 2021, the drama costume and props making skills (opera helmet making skills) applied by Xicheng District, Beijing, were approved by the State Council to be included in the extended list of representative items of the national intangible cultural heritage.
