Liu Yang, China – Once on the brink of extinction due to strict environmental regulations, China's fireworks industry is experiencing a resurgence thanks to drone technology. This transformation is most evident in Liu Yang, a city in Hunan province that has long been known as the "fireworks capital of the world."

For centuries, Liu Yang has been at the heart of the global fireworks industry. Its unique, undulating terrain naturally absorbs the shock of explosions, and the region is rich in sulfur and saltpeter, essential ingredients for fireworks production. However, in 2013, China's government imposed a ban on fireworks to combat air pollution and reduce fire hazards, dealing a severe blow to the industry. Thousands of factories were forced to close.

But in recent years, the industry has found new life through drone technology and "cold fireworks" displays. Liu Lian, a fireworks industry veteran of 20 years, told the South China Morning Post that drone fireworks have become a new growth driver. "The industry seemed to be in decline, but drone fireworks have created a new momentum," Liu said. "The number of related companies is increasing, and sales are also growing."

Data from Chinese business information provider Qichacha shows that the number of fireworks-related companies registered in 2023 increased by 79% year-on-year, reaching a 10-year high. As of last month, there were 73,600 registered fireworks-related companies.

Liu Yang has embraced this technological shift, hosting 50 advanced fireworks events last year and attracting over 3.8 million tourists, generating 11 billion yuan ($1.6 billion) in tourism revenue. Drone-powered fireworks displays offer greater precision, safety, and reduced noise and smoke.

China's drone fireworks technology has also gained international attention. Last year, a Chinese drone company from Shenzhen created a spectacular fireworks display using hundreds of drones above the Palace of Versailles during the Paris Olympics. The company is expanding its overseas business, with performances in over 20 countries, including the United Arab Emirates, the United States, South Korea, and Japan.

However, the transition to drone fireworks is not without its challenges. The South China Morning Post warns that technical issues such as weather, signal interference, and equipment failures can jeopardize the safety of these shows. A recent incident in Orlando, Florida, where a drone crash injured a seven-year-old boy, highlights the potential risks.
