According to the Hue Monuments Conservation Center, fireworks displays at Ky Dai relic site take place every week on Saturday evenings and major holidays.
Each supercharged gun is equipped with a maximum of 9 shots. With a total of 8 guns available in Ky Dai, the maximum number of shots per night is 72.
The Hue Monuments Conservation Center said it will try to adjust the performance to last up to 70 seconds - longer than the previous 40-second time, bringing a more complete experience to the audience.

Fireworks display is one of the regular activities. The program takes place every Saturday night in Ky Dai, creating a vibrant highlight for Hue heritage space at night.
People and tourists visiting Dai Noi at night should go from Hien Nhon gate and park their motorbikes on Doan Thi Diem street. The car was parked at Eo Bau Nam Xuong parking lot according to the instructions of the authorities.
In addition to watching the fireworks display at night, visitors should not forget to spend time visiting the Hue heritage space.
Inside Hue Citadel, there are many festivals recognized as national treasures.
The 9 cannons were divided into the "four Times" group consisting of 4 Spring - Summer - Autumn - Winter and the "U hanh" group consisting of 5 Gold - Moc - Thuy - Fire - Tho.
During the Nguyen Dynasty, the gate of the festival was placed in front of Ngo Mon Gate - the main gate of the Imperial Citadel, in two rows of the Arsenal. Currently, 9 cannons are placed at The Nhon Gate (Ngan Gate) and Quang Duc Gate (Sap Gate) of Hue Citadel.

The Nine cannons, also known as the Nine cannons of the Commander-in-Chief, consisted of 9 bronze cannons, cast from January 1803 to January 1804, under the reign of King Gia Long (1762-1820).
The 9 guns have a symbolic meaning for the court documents of the royal court, and are also a decorative and power- exercise device, contributing to the solemnity of the capital and the royal palace.
