Can someone tell me the history of this manhole cover?

It’s absolutely ridiculous – can’t they think before starting work?

Old fish, settle in for a long chat – let me explain in detail: Several years ago, this manhole cover was originally a demon; because it offended one of the designers from a certain large building project, a curse was cast upon it, sealing it away within the blueprints. Who would have thought that, in a rush to get the materials one day, I handed over these sealed blueprints to the construction team. The construction workers were completely puzzled; they couldn’t figure out the intricacies in those drawings and didn’t know where to start to implement them. Coincidentally, some migrant workers glanced at it and said they could carry out the construction according to the markings on the diagram. Seeing everyone’s surprise and doubt, they issued a pledge to prove their sincerity. Immediately afterwards, a manhole cover was taken and divided into three pieces, which were then fitted into the steps, exactly as shown in the drawings. Everyone exclaimed in amazement; a master lies among the common people – reward shall be given according to military orders. That night, the migrant workers brought wine and meat to the manhole cover and offered them as an offering. Muttering to oneself: Look straight at the third segment, look sideways at the third level, look down at the circle – what a hard fate for the manhole cover. . . .

Too kind, too kind! Add some fun to a dull life; otherwise, it’s too boring!

I guess it’s not the manhole cover’s fault, but the steps’ fault

Do you mean to provide a detailed drawing of this manhole cover, or should it state that it should be manufactured according to the actual conditions?
