Introduction to Li Tian: Li Tian, the founder of Chinese fireworks. When the plague was prevalent, Li Tian used small bamboo tubes to hold gunpowder and ignited it. He used gunpowder smoke to disperse the miasma in the mountains and reduced the epidemic of the plague. As a result, firecrackers quickly became popular. Li Tian was therefore regarded as the founder of the fireworks and firecracker industry. In Li Tian Park in Shangli County, there is a bronze statue that is 12.8 meters high and weighs 2.5 tons.
