What do the 64 hexagrams stand for and how are they combined?

Each of the 64 hexagrams is formed by overlapping two hexagrams. Among them, the eight basic hexagrams are Gan, Kan, Gen, Zhen, Xun, Li, Kun and Right, and each single hexagram consists of three yin or yang hexagrams. Starting from the bottom, you will be the first and second.

The first representative location and age group 10 to 20 years old; Two delegates and the age group of 30 to 40; Sanyi stands for Tianhe, representing the age group of 50 to 60. The upper, middle and lower levels also represent the talents of heaven and earth.

The hexagrams consist of two identical or different single hexagrams. There are three flaws in a single flaw, and two flaws are six flaws. The first two are land; Three stubborn and four stubborn people; The fifth is the highest priority. From bottom to top, the first line indicates one to sixty years old respectively. Each hexagram represents ten years, and six hexagrams are sixty years (a flower). The yang is called nine, and the yin is called six. The first divination is called the ninth day and the first divination is called the sixth day. If the upper body is yang, it is called wine, and if the upper body is yin, it is called shangliu. Two three four five. If it is Yang, they are called 92, 93, 94 and 95 respectively. Two, three, four and five are yin, which are called 62, 63, 64 and 65 respectively. Call nine to know it is yang, and call six to know it is yin. In this way, we will know that it is Yang and it is Yin. We began to draw hexagrams, from the first two hexagrams to the last one, with nine as yang and six as yin, and soon we knew what hexagrams were.
