The eight-character fate does not mean that it is needed without five elements. The key is that the fate can be balanced circularly, and the five elements of the league bureau need to be supplemented. Your son's eight characters are from the official position, and he works hard every month. If you have soil, you will refrain from being a financial star, and if you have gold, you will refrain from being a financial star. Therefore, it is not appropriate to make up the gold and soil. I suggest you replenish water, which will not only make the fortune star prosperous, but also make the moon dry.
This is a good horoscope, reminding you not to be a quack-like fortune-teller, and to make up the other five elements casually, thus ruining the rare fate.
