Stepping into the Cantonese opera hall of the Hong Kong Heritage Museum, the veteran Cantonese opera hat accessory Chen Guoyuan was dressed in a Tang costume embroidered with gold thread, paired with a red scarf, appearing energetic. Despite being over a year old, he still walks steadily and calmly. When it comes to the Cantonese opera hats and costumes displayed in the museum, he is full of energy and has a loud voice. Chen Guoyuan, known as the "living dictionary" of local Cantonese opera costumes in Hong Kong, has been involved in hat and costume production for over 60 years. Many veteran experts have retired one after another, but he still silently sticks to his "behind the scenes stage". Actors shape characters on stage, and if their appearance does not match, it is difficult to convey the unique charm of the character to the audience. Headwear and costumes are not only external decorations for actors, but also concrete expressions of the character's soul Chen Guoyuan said. (New Society)
