The first day of July should be taboo.

The ancient book says: "The Congenital Festival, the first year of Song Dazhong Xiangfu, takes the first day of July as the Congenital Festival and has a five-day holiday. Seven days before Jingzhou, the government, the army and the prison, a Dojo was set up (Jiaào prayed to the gods) and the slaughter was stopped; On holidays, scholars hold banquets, and the capital is brightly lit. "

The first day of the seventh lunar month is a congenital solar term, and it is said that the gate of hell is closed. According to the older generation, the first day of July is the day when the gates of hell are wide open. From the first day of July to the thirtieth day of the death gate, ghosts from the underworld will flock to the dead, and people will hold a "Purdue" in July to prevent it by chanting.
