In the ancient steel town of Nuanquan in China's Hebei province, Chinese New Year brings a different kind of fireworks display each year.
The blacksmiths in the town perform a 500-year-old local tradition called "Da Shu Hua" (literally, beating trees into flowers), where they throw molten iron onto a high city wall. The practice is also known as "poor man's fireworks", because it's been said that the blacksmiths started doing this because they couldn't afford real fireworks then.
The iron reaches a temperature of over 1,000 degrees Celsius, and the blacksmiths wear sheep's fur and straw hats to protect themselves during the performance. They use wooden ladles that have been soaked in water for days prior, and the ladle throws up sparks the moment it touches the liquid metal.
The metal hitting the wall creates an even larger spray of sparks, and the arc of the spray resembles tree canopies, giving the festival its name.
