What does divination mean in Zhouyi?

The hexagrams in Zhouyi refer to the origin of hexagrams, and the latter hexagrams refer to how the origin will only change in the following different changes. Just like a seed, no matter where it is planted, the nature of the fruit will not change, just because of the influence of external conditions, it may not bear fruit. This is an example. In the divination, it means that the gentleman is constantly striving for self-improvement, which shows the essence of the gentleman. However, different external conditions have different results. Or hide or publicize, or be cautious or fight. If the external conditions are right, you must show your talents when you see the dragon on the field. If you don't know the development behind the good events outside, you must secretly accumulate strength and wait for the opportunity. In other words, divination is the essence of things, while divination is essential diplomacy.
