The Chinese traditionally celebrate the Spring Festival holiday with fireworks and firecrackers, as custom dictates that the noise and fire created by the pyrotechnics can drive away evil spirits.

In recent years, more and more Chinese cities have implemented stricter firework controls in urban areas during Spring Festival due to environmental and public safety concerns.
