When I was a child, I liked to listen to storytelling very much. I often listened to Dan Tianfang Shan Lao talking about the dressing of chivalrous people. I only knew what "wearing a hero's coat, pulling three-pointed arrowhead leaves upside down" and so on. Of course, the arrowhead leaves there have become the fashionable dressing of chivalrous people, but it seems that there is little significance in storytelling in Beijing opera, but some chivalrous dramas still seem to follow the dressing of "pulling arrowhead leaves upside down" and so on.
Personal knowledge is really limited, so just answer these questions.
I am deeply sorry!
