If there was a manhole cover right in front of you, would you step over it or just step on it? If you ask northerners to answer this question, the replies they get are basically all about crossing over or bypassing.
But if this is the case, how should you respond?
People say that the manhole cover will eat people, and some people think that stepping on the manhole cover will be contaminated with bad luck, because the bottom of the well is dull all the year round, it belongs to the place where dirt and dirt are hidden. Especially the sewage manhole cover, you can smell the stench when you stand next to it. Therefore, the elderly will tell the children in the family to avoid them when walking, so as not to get into bad luck. Over time, people became convinced of this statement.
Although this is superstition, it can be explained from a scientific point of view.
Depending on the region and the application, the structure and depth of the manhole cover will vary. In some deep places, the inside of the manhole cover can even be ten meters deep, and if you fall into it, you will have to peel off the skin if you don't die.
Although most manhole covers are not so deep, they are basically more than a meter. It's hard to tell if it's covered or not just by looking at it from the outside, and you can only tell how loose it is by stepping on it.
And if you are unlucky and happen to come across a manhole cover that is not tightly covered, then the whole person will fall into it in an instant. If you react quickly enough, you can still hold your hands on the periphery of the manhole cover. But the leg will definitely get stuck in it, and it can be a sprain or a broken bone.
There are also manhole covers that have already been covered with cracks in the wind and sun for a long time, and this situation is not visible from a distance, and by the time something is wrong, it will be too late.
Therefore, for safety reasons, it is best to walk around the manhole cover. So, did your family say that the manhole cover should not be stepped on, and if this happened, how would you deal with it?
