In the eight characters, the Japanese yen stands for an individual, equal to me (robbing money), equal to Yin and Yang, different to rob (robbing money), equal to wealth, equal to partial wealth, different to positive wealth, equal to official killing, equal to seven killing, different to official killing. For example, someone's eight-character yen is jiamu, jiamu is male, and jiamu is female. Both are wood, and yin and yang are different. A nail is a Japanese yen robbery. Wood and soil are fortune stars, yang, and soil is yin soil for positive wealth. Jin Kemu is Yang, so Geng Jin is a seven-kill.
Whether robbing money, wealth or killing seven people, there is no good or bad in itself, which depends on the measurement of the likes and dislikes of the eight characters.
