It is better to give priority to the direction of one's own lack of eight characters, such as finding nonyl armor for water-deficient wood, and then finding yin and yang to make up. Eight-character balance, one side is strong and the other is weak.
The ancients said: the eight-character pure yang, gram mother; Eight-character pure yin, gram father. People with pure yin in the eight characters have a deep personality and like to hide something in their hearts.
