The Bazi is centered on Yongshen. Without Yongshen, gods such as Luma, Rigui, and Wenquxing are useless and can only be used as a reference in practical applications. For example, in this horoscope, Geng Metal is born on the noon day, the body is weak, and the great luck is earth. If the earth is born in metal and releases fire, the life will be smooth and auspicious, but the wood will be avoided. If the fire is strong, the wood will be in the wood, and the wood will produce fire, which is unlucky.
