At the Xa Tac Esplanade - the place where the ritual takes place - there will be altars, incense, offerings, guards, officials of all kinds, consular officers, and deacons... The main rituals: Quan Tay (the king washes his hands); Dang Huong (offering incense); Nghinh Than (welcoming the gods); Dien Ngoc Bach (offering jewel and silk); Hien Tuoc (offering wine); Truyen Chuc (reading the will); Tu Phuc Lo (blessing); Triet Soan (preparing food)...
According to Kinh Le, the Xa Tac Esplanade built must have a "Xa" foundation for worship. The two floors of Xa Tac Esplanade are located on a large, square land, surrounded by stone walls. On the south side, there is a screen, on the three sides of the east, west, and south side, there is a small door, and on the north side (front), the three-arched-entrances gate. In the garden of the Esplanade there are pine and apricot, the two sides of the road from the bottom floor lead to the gate plant two straight rows of calophyllaceae trees. Therefore, Hue folklore has a saying: "Van Thanh grows pine/ Vo Thanh cultivates catappa/ Look at the two rows of calophyllaceae of Xa Tac". In front of the three-arched-entrances gate, in the north, there is a road separating the esplanade from Xa Tac Lake. The lake is wide, square, side 57m, with clear blue water and the shadow of Xa Tac in the lake.
Referring to the Rituals of Xa Tac, each era is different, but in the Nguyen Dynasty, the Xa Tac Ritual was organized by the court. Before the ritual, the roads from the Citadel to the Xa Tac Esplanade had to be cleaned up. Before that, from the king to the mandarins, anyone who participated in the rituals had to fast to keep themselves clean.
In order to prepare for the rituals, the Ministry of Rites must take care of repairing and fully arranging offerings, altars, and incense. On the main ceremony, the two sides of the road from the gate of Ngo Mon had soldiers and flags standing majestically, torches all night. On the altar, in addition to the usual ritual and worship items, there is also a triple sacrifice of three animals: buffalo, goat, and pig.
The army of more than 700 people full of guards, mandarins, soldiers, music teams, Bat Dat dancers, elephants, horses, drum bells, hammocks, parasols, fans, and flags... depart to the village. After that, the Ngu Dao carried out the ritual in a solemn and sacred atmosphere.
In front of the great altar, the king wore the nine-dragon crown, the royal robe, and the jade belt, as the priest. Behind the king, the mandarins wear a neat costumes, the lines are straight, and the faces are solemn, respectfully bowing their heads to worship. The ritual takes place in a solemn atmosphere with many respectful rituals. Immediately after the official ritual, when the king had returned to the palaces, the people were allowed to go up to the esplanade to offer incense for the rain and wind to harmonize, the harvest was plentiful, and the life was full.
