What is the difference between Yin Na, the main branch of the five elements in Sixty Jiazi? Which is more important in the influence of horoscope?

We know that "eight characters" used to be called "four pillars". Four-column prediction does not use today's eight-character fortune-telling method, but uses four-column Yin Na. If Yin Na's fortune telling is useless, what would ancient gentlemen use to tell their fortune? I've seen some fortune tellers who are still using them, and they use them very well. Yin Na's role in fortune-telling lies in that we haven't found it yet, and we haven't made good use of it. Let me talk about the superficial experience of personal prediction. For example, when Yin Na is a fire, the sun is dominated by the mountain fire in Yihai, JOE. What are the characteristics of mountain fires? I am on a high mountain-lonely, everyone can see you-dazzling, illuminating others, there is no way to contribute. Once the snow comes-alone, trapped. There is a fire in Bing Yin Ding Mao's stove. The fire in the stove needs the help of the wind. Introverted, selfish, depressed, sleepy (limited). The good thing is that someone takes care of you, cares about you, and so on.
