Shaoyang, Laoyin, Shaoyang, Shaoyin, Shaoyin, what is Lao Yang's divination?

Take one day as an example. It is sunny in the morning, Lao Yang at noon, cloudy at night and Lao Yang at midnight. It can be understood that the sun began to rise in the morning, and the sun was just beginning to come out, and the sky began to heat up slowly, but it was still cold below, so the sun was missing at this time. At noon, the whole thing began to heat up. At this time, Shaoyang became Lao Yang. At night, when the sun goes down, the sky begins to cool, but the ground is still very hot. This is the time when Lao Yang turns into Shaoyin, and it turns into Laoyin at night. I ching believes that the universe is constantly moving and changing, and it keeps moving back and forth. This change has produced four main stages, namely four images, represented by Shaoyang, Lao Yang, Shaoyin and Laoyin respectively.
