Ordinary fireworks. "Flower decoration" is also called fireworks, commonly known as fountains and waterfalls. Compared with dangerous varieties such as Sanhuan (small firecrackers) and foot line, "shelf flower" is safer, so its sales volume is larger. The ingredients of "shelf firecrackers" (Dihong) still contain potassium chlorate, and there is still the risk of accidents when used improperly, so it is also regarded as one of the more dangerous types of firecrackers.
