Hefei people have two characteristics in the New Year: one is to "burn incense and charcoal"; Second, firecrackers continued all night, and the festive atmosphere was very warm. "Burning incense charcoal" means that after cleaning the dust on New Year's Eve, every household should pour red charcoal with vinegar in the house. When the smoke rolls, it is filled with smoke, which can purify the air, ward off evil spirits and avoid disasters. After the New Year's Eve, firecrackers exploded, which lasted from evening to the next morning.
