I think I didn't understand it carefully before, or there is something wrong with my memory. When I came to the bomb shelter (the one in the north), I found that there were two, one in the south and the other in the north. Sure enough, as I hoped, the openings of these two air-raid shelters were still locked by iron gates, and only a small part of the internal environment could be observed through the fence gap above the iron gates. Although you don't enter the cave, you can obviously feel the great contrast with the outdoor environment by stopping at the entrance. Because the air-raid shelter building is low and concealed, some Shi Zhuan inside has turned from red to black and moldy in the dark and cold environment, and it can be clearly seen that water drops are oozing from above the iron gate. After spying on the dark bottomless passage inside the air-raid shelter, I wonder if I can have enough courage to enter even if it is open, whether I will soon become nervous and at a loss after entering, and whether I can return safely and see the light of day again. The more I think about it, the more I get scared.
As for the origin of building this air-raid shelter, I have not found it in the limited local literature at hand, but it is recorded in the ninth volume of Donghe Literature and History, Donghe District Memorabilia, during the period of 1969: "165438+124 October, Donghe District Revolutionary Committee made efforts to implement President Mao Zedong's". Later, I found an article "Memory under the Surface of Air-raid Shelter" on the Internet (the article came from Freepost website), in which a passage was introduced in detail: "According to the information obtained by the reporter from Baotou Civil Defense Office, the construction of air-raid shelter in Zhuanlongcang Science Resort began at 1970, organized by Baotou Civil Defense Office and Donghe District Civil Defense Office, and the construction of each unit was gradually completed.1970. The buildings in the cave are composed of stone walls, brick arches and stone arches. There are 6 entrances and exits in the whole section, 2 meters wide and 2.2 meters high. Mainly used for personnel evacuation and concealment in wartime. According to the personnel concealment standard per square meter 1 person, the wartime caves can accommodate 4000-5000 people to take refuge. "From the introduction, I generally know that the design structure of this air-raid shelter is much more complicated than I thought, especially the length of the tunnel. The distance close to 2.5 kilometers is not close in normal walking. Imagine how long it will take to walk in the tunnel. It is also mentioned that the tunnel has six exits, two of which are in front of me. Where are the other four exits? I don't know yet. Another question is where the "head kiln" mentioned in the article is, and it is here now.
I don't regret not being able to "walk" in this bomb shelter in the end, but I feel a little "lucky". After all, the purpose of fortification outside the cave is for personal safety and to prevent accidents, so it's good to see it, and don't add chaos to others and society. In a word, I hope this rare and historic civil air defense project can be completely and permanently preserved.
