4.3 Why should fireworks be set off?

Setting off firecrackers in Tomb-Sweeping Day is a folk tradition to drive away ghosts and evil things. Setting off firecrackers after going to the grave has two folk meanings.

Tomb-Sweeping Day began in the Zhou Dynasty and has a history of more than 2,500 years. Tomb-Sweeping Day is first of all a very important solar term. As soon as Tomb-Sweeping Day arrives, the temperature rises, which is a good season for spring ploughing and planting. Therefore, there is a proverb "Before and after Qingming Festival, plant melons and beans". Later, as Tomb-Sweeping Day and the Cold Food Festival approached, and the Cold Food Festival was a day when people were forbidden to burn graves, gradually, the Cold Food Festival and Tomb-Sweeping Day became one.
