Steel flowers dance dragons, and the dragon dancers go shirtless. Why can't they be burned to death by steel flowers?

The person who "plays steel flowers" is a unique skill handed down from his ancestors. Every time I came to power, a dozen Tongliang people held a small iron drum weighing more than 20 kilograms, with steel and coal burning iron under it. The combustion temperature is 1200℃. After about 4 hours of preparation, a bucket full of iron blocks will become a red crucible for boiling molten iron during the performance. During the performance, one person scoops up a hot metal bean with a small bamboo spoon and throws it into the air, while the other person quickly looks at a board as big as a ping-pong bat and draws it. The scattered "splash" was scratched out in the air and burned again.

The molten iron scooped out every time will be more dispersed after being hit with a wooden board, and the more dispersed the molten iron, the better it will look. Even if it sticks to the body, it will fall off quickly.
