What is the meaning of refined words in calligraphy mounting?

Decorative ribbon on the painting axis. Also known as "shock rope". Used on two-color wide painting axes. The early swallow-scaring belt was a fixed and movable ribbon, which fluttered with the wind and blew insects to scare swallows. Later, it was gradually fixed on the painting axis for decoration. The silk with the same pattern as the head of heaven and earth and the same color as the frame are generally used for the surprise swallow belt.
