To achieve the goal of "simplicity", the number of fireworks displayed at the opening ceremony was one-tenth of that of the 2008 Olympic Games

In order to achieve the goal of "simplicity", the total number of fireworks displayed at the opening ceremony of the Beijing Winter Olympic Games was one-tenth of the opening ceremony of the 2008 Olympic Games.

According to statistics, the high-altitude salute bomb is 1800 rounds, the low-altitude bouquet is 3221, there are 9 groups of high-altitude special effects, and there are 17 groups of low-altitude special effects. Cai Canhuang mentioned that in order to achieve simplicity and frugality, the fireworks display only participated in two rehearsals, and the two rehearsal fireworks were 20% and 50% of the total amount, respectively.

Although the number of fireworks is less than that of the 2008 Olympic Games, the challenges facing the firing teams are still significant. Walking on a staggered steel beam only 1 meter wide at a height of 69 meters above the nest, the construction crew was greeted by a northerly wind of 3 to 4 and a gust of 7. Cai Canhuang said that in winter, the operation on the top of the bird's nest is more difficult than other seasons, and the two rehearsals have caught up with the snow, and the steel beams at the top of the bird's nest are very slippery, and the security team has made a lot of plans for this. The construction personnel adopt a group operation method, a group of two people, the front one to sweep the snow, the back one to carry out the operation, in order to ensure the equipment, product installation efficient and smooth.
