  This is the opening and closing ceremonies of the Beijing Winter Olympics in their eyes: there are 50 grids inside the National Stadium (hereinafter referred to as the "Bird's Nest"), the highest is at the top of the Bird's Nest, the place closest to the fireworks, and the lowest is 18 meters underground, where hidden The Ice Cube, the Olympic Rings, and the Torch Platform that amaze the world; the beautiful ice waterfall is made up of more than 40,000 electrical components and countless lines; every spark that falls from the fireworks makes their nerves tense. , dare not relax.

  The fire and security team for the opening and closing ceremonies of the National Stadium Bird's Nest is their common name.

The team, with an average age of 22.5 years, regards the 300,000 square meters of the Bird's Nest as a position that it has to defend.

During the Winter Olympics and Paralympics, the team eats, drinks and lives in this position.

They took care of every detail related to firefighting.

Let's listen to the story of "Flaming Blue" together in the live broadcast room of "China Youth Daily".

  "Go to the ground", the team leader Yao Guocai used these four words to describe the team.

The top of the bird's nest, the middle of the mezzanine, the ground warehouse, the fireworks position, and the 50 grids covering the inside of the bird's nest all have the figure of "flame blue" sticking to it.

  At the top of the bird's nest, the "flame blue" is on duty for up to 12 hours, and it takes eight or nine hours when it is less.

In the fireworks field, they must prevent secondary disasters from falling fireworks, and protect the membrane structure on the top of the bird's nest from being affected by fireworks.

  There is a bunker 18 meters underground that the audience can't see.

There are large core devices such as the Ice Cube, the Olympic Rings, and the Torch Platform hidden here. Many key props for the opening and closing ceremonies are concentrated here.

At the opening and closing ceremonies of the Winter Olympics, the warehouse was filled with surprises that could bring aesthetic experience to audiences all over the world.

But for firefighters, what they see is a very high risk of electrical fires behind a large number of applications of acousto-optical technology.

  "The basement is the focus of our prevention and control. The air here is thin and there is less oxygen." Yao Guocai said, "From the design of the fire protection plan in the early stage to the hourly fixed-point inspections in the later stage, our stationing has not been interrupted."

  In order to present a unique visual effect, the super-large 8K ground screen in the center of the Bird's Nest is composed of more than 40,000 LED modules, covering an area of ​​10,552 square meters. A 1,200-square-meter 8K LED screen is erected above it. The largest ultra-high-definition LED 3D stage.

  Behind the over 43,000 LED screens are complex electrical circuits and components.

The erected LED screen has a beautiful name "Ice Waterfall", is 59.2 meters high, 20 meters wide, and has a total weight of about 730 tons.

Fireworks bloom over the ice waterfall, like a song of ice and fire.

However, under the beautiful scenery, every falling spark made the nerves of the fire and security personnel tense.

  Zheng Zhiyong, head of the grid grid of the ice waterfall on the stage, recalled that on the side facing the audience, the ice waterfall displayed a shocking visual effect through the large LED screen.

However, on the other side that the audience can't see, firefighters have to wear thick duty coats, carry fire blankets and water-based fire extinguishers on their backs to climb to the highest point of the icefall on duty.

Climb up and down with bare hands, and a pair of gloves is scrapped.

  This point is ventilated in all directions, and each time you are on duty, you must stick to it for at least 12-18 hours.

To this end, the seven duty officers would rather eat less and drink less and wear "diapers", but no one has ever complained about it.

  On the evening of February 4, as soon as the opening ceremony of the Winter Olympics ended, the Bird's Nest began to prepare for the closing ceremony of the Winter Olympics on February 20, and the dismantling of the ice waterfall began immediately.

  "The demolition of the ice waterfall has created a miracle." Yao Guocai said, "It took three or four months to complete the construction, but the demolition took only 102 hours, 42 hours earlier than the original plan." 3100-3600℃.

Firefighters understand better than anyone that this temperature can melt everything, which means that any fire prevention measures are ineffective in the face of such heat.

  Zhang Yuxing, deputy head of the fire-fighting and rescue team, said: "During the demolition, our fire-fighting and disposal team was on duty 24 hours a day, changing shifts every three hours, from day to night, and from night to dawn."

  There are 1,434 kinds of props in the opening ceremony of the Winter Olympics, and more than 1,500 sets of 16 kinds of power generation clothing. The fire security team needs to conduct risk assessment and sampling experiments for each prop and clothing.

Every product needs a test report to strictly control the quality.

There are more than 27,000 closing ceremony props, especially the highlight props of the closing ceremony - lanterns.

  In the eyes of firefighters, a lantern is a source of ignition.

They have performed drop experiments and puncture experiments many times to ensure that the battery is relatively reliable and does not produce bulges.

  People are another important factor in ensuring fire safety.

Yao Guocai introduced that 100% of the actors in the opening and closing ceremonies have been trained, and the security personnel have been trained by "one police officer and six officers".

  "There are 1,268 rooms in the bird's nest. I can't remember how many times I checked it." He said.

  In order to ensure the Winter Olympics and Winter Paralympics, the first batch of team members will be stationed on January 25, 2021.

After nearly 400 days of perseverance, everyone wrote their own stories in this 300,000-square-meter venue.

  Zhang Yuxing was one of the first team members to enter the Bird's Nest.

As the deputy head of the fire extinguishing and disposal team, Zhang Yuxing's duty after the start of duty is to be on duty on the fire truck for defense.

  From the rehearsal to the official performance, Zhang Yuxing and his colleagues have always been behind the scenes to guard the world-renowned splendor.

They can't go live, or hot or beautiful music becomes the background sound of their work.

Zhang Yuxing said that from the theatrical performance celebrating the centenary of the founding of the Communist Party to the opening and closing ceremonies of the Winter Olympics, being able to participate in the event in a special way on the fire truck is the pride of his profession.

  This is Zhang Yuxing's eighteenth year as a firefighter.

In December 2021, the first-level firefighters expired. Zhang Yuxing did not know whether he was going back to his hometown or whether he would continue to stay in the team.

However, he expressed his determination to the party branch early in the morning, no matter what the result is, he will guarantee the successful completion of this task.

  This well-trained and well-mannered fire and security team has been recognized by all parties.

During the rehearsal, the young actors in the Dove of Peace section of the opening ceremony forged a good friendship with the firefighters. During the Chinese New Year, the children sent handwritten blessings and letters of thanks to the firefighters.

  This lasting and practical effort was also noticed by the director team of the opening and closing ceremonies.

Director Zhang Yimou specially asked for a group photo with the fire safety team.

"He said that our efforts make the splendor more exciting, and there is always safety behind the splendid." Yao Guocai said, "Sha Xiaolan, the chief director of the closing ceremony, specially invited firefighters to participate in the performance of the closing ceremony. This is not only for The affirmation of our team is also a recognition of our profession and the fire rescue team."

  The curtain of the Winter Olympics has come to an end, and the curtain of the Winter Paralympics will begin.

The venue for the opening and closing ceremonies of the Winter Paralympics is still set at the Bird's Nest.

People are looking forward to the surprises that the opening ceremony of the Winter Paralympics will bring.

And the guarantee behind this full expectation is still "flame blue".

The excitement will continue, and their perseverance will not stop.
