New Year’s Eve 2019 Media Corporation of China gala concert. Amazing, wonders Russian blogger Alex Exler (exler.ru) in his post, and I quote, imprecisely translated, “How is it possible to set such a large-scale spectacle, where a huge number of people not only move synchronously (music usually helps here), but also gets to the right point at any given time, and very precisely.”
I have found a plausible explanation in one of the comments to the post. Roughly translated: The choreography of movement here is rather simple: at each given moment of time each Chinese should know exactly who are the other Chinese he should run after, and beside which Chinese he should stop. And only a few Chinese should know exactly where to run and where to stop.
But then again, they aren’t simply synchronously run and stop en masse. They perform en masse!
