Four pillars and eight characters: Ren Chennian, Geng Xu Yue, Wu Shenri, Xin Youshi. Birthdays belong to the soil
Five elements: gold 4, wood 0, water 1, fire 0, soil 3.
These eight characters, the five elements lack wood and fire, and must be added. I suggest that when naming children, use the words next to wood and fire. For reference, I wish the baby a healthy growth.
