The director admits that the filming experience shattered his stereotypical notions about the fireworks industry. The application of modern technologies such as chip technology and intelligent machinery in fireworks production helped him realize that it is no longer a labor-intensive traditional industry.

Utilizing drones, this documentary tracks the entire dynamic process of fireworks, from ascent to full bloom, offering the audience an up-close observation of the display.

"This provides a perspective entirely different from our usual view of fireworks from the ground, making them appear more impactful," he says.

"From the 'giant footprints' shaped fireworks at the opening ceremony of 2008 Beijing Olympic Games to the 'Five Rings' fireworks at the Beijing 2022, fireworks have become a means of showcasing China's national image," says Zhu.
