What does the triad in the eight characters mean?

The triad of eight characters refers to the triad of heavenly stems or earthly branches in eight characters. Trinity refers to the relationship between three adjacent heavenly stems or earthly branches, which is called "Trinity". For example, A, C and E are adjacent to each other to form a triad. According to the eight-character relationship, the trinity relationship can play a very good role in improving wealth, interpersonal relationship and life fortune. However, it should be noted that if the heavenly stems or earthly branches formed by the triad are not suitable combinations of five elements, they may also have negative effects.
