The procession draw water-termed "sacred water"- from the well at Mau Temple, dedicated to Giong's mother, and carry water contained in two big jars to Thuong Temple, dedicated to Giong. The villagers take water in order to wash and clean the weapons of Giong's troops, and pray for good weather and a bumper crop.

On the 8th day: The head of the giap (a village of organization gathering its male members according to their ages) and the notables from the four villages hold an review of troops representing Giong's army.
On the 9th day: The main festival day is marked in the morning by a procession carrying the flag from Mau Temple to Thuong Temple. Its rites are similar to those of the water procession. When the procession arrives at the temple, it is greeted with a ritual while the "troops" perform a ceremony and military display in honor of Saint Dong. In the end, they stand in rows before the altar of the Saint and pay their respects to him.
At 10 a.m, it comes the "catching tiger" game played by the group of dancers. At the same time, at the "enemy camp" near a lotus pond in Dong Vien Village, 28 female fighters of the Yin army sitting on their palanquins, surrounded by spectators, are ready for the battle.
At 1 p.m, reconnaissance groups report that the enemy troops have occupied the areas of Dong Dam and Dong Vien. The news is greeted by three salvos of drumbeats which signal the decisive hour comes. While the troops line up in rows waiting for the battle order, the group of singers and dancers perform a song praising Giong as the general sent by God to help the people repel the aggressors. As the song ends, the commanders prostrate themselves before the altar, receiving the order from their commander-in-chief and vow to fight to the end. The soldiers shout in chorus: "Yes, we obey the orders" and then start moving.
While marching and pulling horses vigorously, the soldiers shout in unison at the command of an officer standing behind the house. The troops stop at Mau Temple where they bow in respect to the mother of Saint Giong.
As the troops arrive at Dong Dam, they put white wooden horse on the dyke. The commanders come and stand at assigned places around the three mats, which are supposed to be the battlefield.
At 2 p.m, after the troops have been arranged (It means that they have been arrayed in battle position), three salvos of drumbeats resound, followed by deep silence. Then the commander gives the attack signal. The advance guards also beat their drums, signalling that they are ready for battle.
The process of the fight against the Yin enemy is symbolized by a number of rituals performed on the three mats by the flag commander. His movements describe the strength of Giong who can displace mountains and clouds. The last rite ends on the third mat, meaning that the battle has been won. The victory is greeted with drum and gong beats.
The troops, in full order, return to Thuong Temple. They stop for a few minutes at Mau Temple to report the news of victory to the hero's mother. Then they enjoy a feast.
The Yin army counter-attacks again. Three new rolls of drum and gong resound. All the commanders and soldiers leave their tables, seize their arms and set out for the front, that is the Soi Bia area lying between Thuong Temple and Mau Temple which is occupied by the invaders.
The flag commander performs the three rituals again, with a slight difference. The end of the third ritual is greeted by three resounding rolls of drum and gong beats which signal complete victory over the aggressors. Enemy commanders are taken to Thuong Temple and are made to kow-tow four times before the altar of Saint Giong. Then an "officer" uses a trophy sword to push away the hat and tear open the dress of enemy prisoner. These gestures symbolize the beheading and skinning enemy troops. He also assembles all the trophies for the purpose of reporting the feat of arms to Saint Giong in the back chamber of the temple.
