Iron version fortune telling

This is a China arithmetic. Generally speaking, there is a process of iron plate divination called "timing". According to the expert of iron plate divination, it is because the time provided by the guests is only a rough estimate, not the real time of birth. Iron plate manufacturers have to push the birth time of their guests to one hour, eight minutes and fifteen minutes in an instant to achieve the most accurate inference. The lithographer will type out some articles and then ask the guests if they are correct. After a round of verification, after completing the procedure of "timing and engraving", iron plate makers will start to print other articles, generally including articles on the different ages of six parents. After all the articles are sorted out, it becomes an iron version of numerology.

It is believed that it was written by Shao Kangjie in Song Dynasty, but there is still no conclusive evidence. In the Qing Dynasty, there was a Taoist named Tiebuzi, whose name came from a magical number. His technology was very popular at that time, and everyone was eager for it. It immediately became a famous but mysterious magic number. The "Iron Blood Edition" among the gods refers to the magic number of the "Iron Blood Divination Edition".
