The eight characters are: Renchen, Yisi, Bingzi, Wuxu
The five elements are: water, earth, wood, fire, fire, water, earth and earth
The five elements of this eight character lack "gold". This gold is used as a god and can be replenished.
Another point to emphasize is that horoscopes do not just make up for whatever is missing. You have to look specifically at the missing five elements, whether they are the useful or taboo elements in the entire horoscope.
If you are using Shen deficiency, it is better to make up for it. If the missing five elements happen to be the taboo gods of this fate, if they are supplemented, there will be disaster and misfortune, and they must not be supplemented.
This horoscope likes "metal and earth". Avoid "wood and fire".
