Dong Ky villlage, Tien Son district (formerly, Bac Ninh). The festival which takes place on the 4th day of the 1st lunar month can go on for as many as twenty days.
The procession of firecrackers occurs on the morning of the 4th day. Each of the ten families responsible for the festival organizes its procession of crackers and food for the sacrifice. Small processions gradually join the large one. There are big firecrackers covered with red paper, decorated with motifs of flowers and leaves, hieratic animals: dragon, unicorn, tortoise, phoenix made of cut golden paper. There are also huge firecrackers 4-6m long, with diameters of 40-60cm and 50kg of powder. The main chain of crackers can reach 15m in length. The procession ends when the 5th big cracker and the 5th chain arrive at the communal house. The firecracker contest takes place in the afternoon. It begins with the 5th chain of crackers and the 5th big cracker, and continues in the same order until the first big cracker is exploded. The master, wearing a turban and belt made of red crepe, holds a lit stick of incense. After three drum-beats, he bows three times in front of the communal house, and goes three times around the firecracker: he is going to light. Prizes are awarded to the best crackers and the best chains. The prize winners organize a procession to take home bits of lit firecrackers and their prizes. They celebrate their victory by giving a great banquet.
