The combination of Zhongzheng and Zhongzheng means that the two heavenly stems and earthly branches cooperate with each other, complement each other, and conform to the coordination rules of the five elements and eight characters. It is considered an auspicious combination. For example, Jiazi and Jihai, Bingwu and Gengshen, Wuchen and Guiwei are all combinations of Zhongzheng. In traditional Chinese culture, the combination of Zhongzheng and Zhengzheng is widely used in fortune telling, naming, marriage and other aspects.
