Setting off firecrackers means saying goodbye to the old and welcoming the new, implying a beautiful longing for the new year. People often burn firecrackers during the new year, and firecrackers have the meaning of exorcising demons, ward off evil spirits and eliminating disasters. Therefore, in later legends, "Nian" gradually evolved into a demon, and the sound of firecrackers in every household is to drive away the monster of "Nian".
Setting off firecrackers is a representative traditional form of new year culture, which reposes people's beautiful longing for the new year. The new year is just around the corner. The sound of fireworks and firecrackers gives the new year a strong flavor. Although today's firecrackers mostly refer to firecrackers with gunpowder, the origin of firecrackers is much longer than gunpowder.
