In interpreting the mysteries of the heavenly stems, we have explored the meaning of "A and B": A symbolizes birth, yang and one, represents the spring of the East, specifically refers to January and February, corresponds to wood, and is associated with the trigram. B, on the other hand, represents growth, yin, and two, and is the same as A, which belongs to wood, mainly in February and March in the East. B is softer than A, with a little less masculinity.
C is the third place of the heavenly stem, which has the same attribute as A, but is located due south, and is the land of pure yang. At this time, everything matures, and the yang energy gradually recedes. There are many interpretations of the word C, some say that it is the evolution of the utensil, and some say that it is the image of a fishtail, but there is no exact interpretation so far. However, we can remember the attributes and symbolic meaning of C in a simple way: C is after A and B, and A and B represent the spring in the east, and according to the order of the acquired gossip, C naturally falls in the south and leaves the position. In this way, the attributes of C: south, yang, disposition, fire, summer, and noon are clear at a glance. After understanding the attributes of C, it is easy to understand the words encountered in daily life, such as "C-fire" and "Pay C".
The meaning of D, which is immediately after C, is closely related to C. Ding is not as enthusiastic as C, if C is the sun, then D is the candle flame. It symbolizes lush vegetation, deep-rooted, and more sober and steady. Therefore, Ding Chengbing, belonging to the fire and yin, is located in the south, in the summer, in the absence. Understanding these will be of great benefit to learn more about traditional culture in the future.
