In the eight characters, the sun column represents the yen (also known as the Lord), and the other four columns represent the environment in which the yen is located. If there are branches in the surrounding four columns that have the same yin and yang properties as the yen, then the relationship between these two branches is called "similarity assistance". For example, if the Japanese yen is an Oracle bone and another Oracle bone appears in the four pillars around it, then the relationship between the two Oracle bones is "similar help".
It should be noted that "similar help" is not necessarily a good relationship. Sometimes, similar help may also have an inhibitory effect on the yen, thus adversely affecting the fate of the Lord. Therefore, when analyzing the eight characters, it is necessary to comprehensively consider the relationship between the branches in the eight characters in order to accurately judge the fortune of fate.
