2. Bring beads. Among the people in the Yin-Yang and Five Elements, those born in winter and those in the cold pot, there are more "water" in the five elements, and the relative "fire" is lacking, while those who lack fire in the five elements have used the beads that choose the property of fire and the color of the main fire. As we all know, obsidian is formed by volcanic eruption symbols, so obsidian belongs to fire, so those who lack fire in the five elements can wear obsidian beads.
