In ancient China, emperors wore special crowns called mianguan during big ceremonies. These crowns had tall boards in the front and back, decorated with jewels and strings of beads. The beads hung down like a curtain, sometimes hiding the emperor's face to show his great power and mystery.
Another type was the benkan, used in different times like the Ming and Song dynasties. These crowns changed for special events, such as weddings or sacrifices. They showed the emperor's role as the top ruler, connecting heaven and earth for his people.
East Asian emperors, like in Japan or Korea, used similar styles with chains or beads. These crowns made everyone remember the emperor's importance.
