Let's talk about the zodiac and the constellation first, because they are both 12 units. Cyclic alternation also takes 12 as a cyclic unit, so it has the property of * * * *. As shown in the figure, we set the order of the zodiac on the outer circle of a bell-shaped disk, and then add the small circle of the constellation (which can be rotated) on the inner circle, and we can see the relationship between the zodiac and the constellation. According to the genus, there are three noble people in Sanhe. The so-called trinity is an angle of 60 degrees. There are three * * * in a garden, so the next one in the disc is its triad. Astrology also knows that angles are also emphasized between palaces. 0 degrees, 60 degrees, 120 are all very suitable configurations. So in the small dish, you will see a 60-degree equilateral triangle similar to the outer dish. This is the * * * between them! Secondly, the constellations of 45 degrees, 90 degrees and 180 degrees also have the same situation in the zodiac. There are many wonderful discoveries in the details, so you can explore them yourself slowly.
