The most common method is to use names to supplement. If a child lacks metal in their five elements, they can add elements of metal in their name. Generally speaking, besides characters with "metal" as the radical, characters with radicals such as ノ、口、几、刀、戈、匕、刂、玉、石、皿、西、贝、兑、辛 are also considered as metal. In addition, we can wear ornaments that belong to the metal element, such as gold jewelry. However, it should be noted that not all metal accessories are considered as metal. When wearing them, we need to distinguish carefully and not randomly.

People with a water element who lack metal show no courage or strategy, lack wisdom, have no ambition, do things half-heartedly, are not good at socializing, are petty, cunning, malicious, greedy, lustful, stingy, and may betray friends at any time, with poor relationships.
If the power of metal in the destiny chart is insufficient, the ability to receive energy is delayed and fails, which is called "broken reception." If the metal energy in the destiny chart is insufficient, the wood energy grows too much, the fire energy and dampness combine, and the growth energy further promotes the growth of crops (wood).
Excessive fire energy causes diseases related to the lungs, such as coughing, hoarseness, irritability, and shortness of breath. Sneezing, coughing, and nasal congestion are results of excessive fire energy converting into metal.
Due to factors such as insufficient metal energy in the destiny chart, such as delayed reception energy and unretreated growth energy, the wood loses the control of metal, and the wood and fire harm metal, which can easily lead to imbalances in the body's energy transformation.
