打鐵花 (da2tie3hua1; struck iron fireworks) is a traditional folk firework that began in Henan and Shanxi, first arising in Queshan county, Henan and later circulating through the whole country. It had first appeared during the Northern Song dynasty, and was most popular during the Ming and Qing dynasties.
For Queshan struck iron fireworks, a two-layer pergola is built and covered with willow branches for performances, under which the molten iron is struck up with two willow sticks to create a rain of fire.

(On top of the information in the video, I have some more about its recent history under the cut.)
This is a comment by OP:
Ever since two years ago when I saw the stunning iron fireworks, the notion of striking iron fireworks has always lingered in my mind, but I never made a firm resolution, scared that after an accident, I wouldn't have to ability to bear it. After communicating with Teacher Yang Jianjun's iron fireworks team, they never had much confidence that I could strike them successfully. Teacher said in the past thousand years, struck iron fireworks had only been passed down to men, never women, and he had never taken in a female disciple.
After seeing myself, he thought it was even less possible, and the kindhearted Teacher Yang was particularly afraid of the iron fireworks injuring me. The shixiong* in the iron fireworks team also particularly looked after me, and attentively instructed me how to strike so that the large chunks of molten iron wouldn't splash on my body. My camera operator was completely equipped with 1500 degree fire resistant protective clothing, and we had even searched up the closest hospital's address before starting. Under the pergola we prayed for Taishang Laojun** and grandpa to bless and protect me hahaha
The good thing is all of it went very smoothly, although my clothes now have a lot of holes in them, I have some small burns, and some of my hair was also burnt off, but all of this was worth it. I've finally become the first female disciple in the past thousand years, and a seventh generation inheritor of Queshan struck iron fireworks! I hope everyone who sees this video can be courageous, and I hope the iron fireworks blesses and protects everyone to be safe, sound, happy, and for all things to go smoothly!

On Bilibili, OP expands on the significance of the pergola design:
Let me explain to everyone the pergola of the "National Level Cultural Heritage Queshan Struck Iron Fireworks".
The Supreme Ultimate: The whole pergola.
Yin and yang: The upper and lower layers.
The Three Powers: The two layers of the pergola plus the pole going through the centre. The three spaces are a total of 15 metres tall, containing the meaning of "Heaven, Earth, Humans". This type of expression can also be found in "Mawangdui Han Tombs No. 1 Silk Painting" (马王堆一号汉墓帛画)
The four constellation groups: The four directions.
The five elements: East is wood, south is fire, west is metal, north is water, and the centre is earth. At each of the five directions, five flags of green, red, white, black, and yellow are inserted to represent the five elements.
The eight trigrams: The pergola is separated into the upper and lower floors, and the two sets of four corners are staggered to create eight corners, the same shape as an eight trigram compass.
There are three dos and three don'ts for iron fireworks. Don't strike during bad harvest years, don't strike during national mourning, don't strike during war. [T/N: The three "dos" are do strike during good harvest years, do strike during happy occasions, do strike during prospering years.] In the recent past, natural calamities and man-made disasters have extended into several decades, and the chaos of war continuing year after year. The Daoists had passed away, and no one could build a pergola anymore.
The style of the pergola you see now is because of Teacher Yang Jianjun spending more than ten years doing textual research from all sides and reviving it from that.
