According to the blue lines drawn on the map, a fire truck can pass smoothly in the community. At Qigong Fire Station, Tiexi District, Shenyang City, every firefighter has such a "special" map in his hand. The route above was not drawn by any map company. It was all based on firefighters born in the 1990s at this fire station, using drones to take photos and drive fire trucks, and explored them bit by bit.

Hou Xinming, a firefighter at Qigong Fire Rescue Station, Tiexi District, Shenyang City: Every community will have some basic situation information displayed here. For example, a fire broke out in the building at the community. When we saw it, we entered from here and quickly arrived at the site of this building, in order to reduce the losses suffered by the people.

28-year-old Hou Xinming is a pilot in charge of manipulating drones. This year is his 10th year as a firefighter. The Qigong Fire Station in Tiexi District where he is located is responsible for fire extinguishing tasks in 171 surrounding residential communities. In order to increase the speed of rescue, Hou Xinming and his partners set up an innovation team to find the "optimal route" for fire trucks to enter the community. Before this year's Spring Festival, all 171 communities in the jurisdiction have been drawn.

Hou Xinming, a firefighter at Qigong Fire Rescue Station, Tiexi District, Shenyang City: At such a turning angle, fire trucks cannot pass, and we have not presented this blue line. However, all buildings are reflected, which is also convenient for the fire truck to reach the nearest location of this building. We use the laying of the main line to carry out rapid fire extinguishing and rescue.

Although the map can increase the rescue speed, what Hou Xinming and his team members most hope is to prevent fire from happening. A sentence they often say is, fire protection, there is a defense behind the word "crypton". So when I visited the residential community, I saw the sauerkraut jar placed in the corridor. I always had to do work with the residents to carry the jar into the house to avoid the heavy smoke when there was a fire, which would affect the escape. When I met an older person, I would also like to remind me that I should not forget the three things of "shut off the engine, power off, and gas off" before going out.

In the largest comprehensive shopping mall in the jurisdiction of Hou Xinming, as the Spring Festival approaches, a full range of New Year goods makes it crowded here. Although the safety tips are clearly written, some businesses will inevitably be negligent when they are busy, and accidentally pile up debris under the fire-proof roller shutter. Once a fire occurs, it is very likely that it will not fall normally, causing the fire to spread. In order to ensure that these fire-proof devices can work at critical moments, Hou Xinming and his colleagues will also inspect in advance before major holidays.
