The use of the acquired hexagram.
The emperor was shocked, Qi was Xun, he was separated from each other, he was in service, he was good at what he said, he was dry in battle, he was hard at work, and he was good at what he said.
This is in the "Legend of Hexagrams", according to which "Han Yi" explains the laws of the physical world in the order of the number of images, which is said to have been written by Confucius. This law of order is, of course, expressed by the acquired hexagram, and it should also be said that the acquired hexagram is drawn according to this law.
The simple explanation of these words of Confucius is:
The sun rises in the east, the earthquake is the east, it is spring, the beginning of the year, the beginning of the day (the emperor is out of the earthquake).
Soon it showed its ability to influence all things, and all things grew, and Xun was southeast.
Between spring and summer, the morning (Qi Hu Xun).
In the middle, it is glorious and governed. Departure is the south, the sun is in the middle, and it is summer, and everything is in full development (see each other).
When the sun is westward, or in late summer and early autumn, the vigorous image of nature has been harvested, and Kun is the earth (Zhizhi Hu Kun).
At sunset, it is the mid-autumn weather of the year, when the hexagram has already arrived, and everything begins to enter the realm of yin.
At night, it is also the time of late autumn, when the hexagram of yang energy enters the yin realm, and yin and yang have the phenomenon of fighting (war is dry).
In the middle of the night, when Meng Dong is in the middle of the winter, all things return, in the realm of extreme yin, a yang is in it, this is a new turning point, full of difficulties (Laohukan).
When the night goes to the end of winter, everything in the universe begins to sprout secretly, and new yang energy rises again.
If we interpret the things and things of the world by this law, there is nothing that does not conform to this law. Therefore, it is scientific and reasonable to push the big and small things of the world according to the "Yi" hexagram.
