People burn fireworks to celebrate the Chinese New Year. In Hong Kong traditional ropes of red firecrackers were banned after the riots of 1967 - at least that was the excuse. Firecrackers and high-density urban areas don't go together. Are dead and maimed children worth the rituals of "tradition" ? Instead, Hong Kong developed a new heritage - massive public fireworks displays and laser lights over the harbour. Everyone joins in and celebtates together.
