In Nuanquan Town, Yuxian County, north China's Hebei Province, the intangible cultural heritage performance "Dashuhua" is spectacularly staged.

Dashuhua, which means striking tree flowers, is a local art form in Yuxian County that originated in Hebei Province 500 years ago and has been listed as an intangible cultural heritage in China.

The inheritor splashes molten iron heated to over 1,000 degrees Celsius onto the ancient city wall, instantly producing tree-crown-shaped sparks. Fire trees and silver flowers light up the ancient fortress at night, creating a magnificent and dazzling spectacle.
