The moral of 49 representatives of Taoism

What does it mean to say that the road is fifty, the sky is forty-nine, and the shield is one of them? Let's discuss it together today.

"Fifty avenues, forty-nine days, one shield" first appeared in Zhouyi. The original sentence is: "The number of big swallows is fifty, and it uses nine out of forty. Divided into Er Ru two, hanging as three, "four as four", strange as leap, five years old and leap, so hanging again. "

The original meaning of this sentence refers to a way and variable of divination. There are two kinds of divination in Zhouyi, one is to use tortoise shells for divination, and the other is to take 50 yarrows for divination, take out one and keep 49 divinations. Fifty represents a complete avenue of heaven and earth. Why did you take it out? It means that one is the avenue for the evolution of heaven and earth, and the calculated things are in the avenue, leaving a little change.
