If you don't think this performance was SUPER, pick up a Nine Section Chain Whip and try some of this yourself,,,,,,,,,,,,,,,,,,,,,, just make sure your medical plan is up to date ;-)
Sometimes called a dragon whip, and in Japan, a weapon somewhat similar is called (in English a spike and chain). The performance in this video is the very best I've seen.
It's just a training exercise meant to work on timing and understanding how the chain moves so you're less likely to smack yourself with it. It was never intended to be used in combat.
