What happened to the "gold casting people" in Wei, Jin, Southern and Northern Dynasties?

The so-called hand-cast gold man is a popular method of divination for good and bad luck among ethnic minorities since Wei and Jin Dynasties, and its source has not been verified. Let's try to speculate that the hand-cast gold man's measurement of good or ill luck never started from the Tuoba Department.

It was recorded in the Book of Jin that Ran Min, the mourning king, sent Chang Wei to the state of Yan, and Murong Jun, the prince of Yan, asked him, "I heard that Ran Min cast gold for himself, but it was a pity that it failed. Why does it have a destiny? " In other words, as early as Wei Ran's time, the way of seeking heaven by casting an image had already begun to spread.
