Ancient books say that the sun and the moon work together, and at the same time have an impact on any divination, with great effect. Measure the proximity with the date and look at the moon. The cooperation between Japanese and Chen in divination is basically the same as that in lunar structure.
Li Chen's function of "combination" or "impact" on hexagrams is different from that of Jian Yue. When the moon meets, it is "prosperous" and when the sun meets, it is "stumbling". There is no such thing as prosperity. There are four situations: the tranquility of the prosperous phase is dark when it meets the sun, and the tranquility of lifeless prisoners is broken when it meets the sun; The vigorous phase moves more and more when the sun washes away, and the prisoners who are released from prison are lifeless when the sun washes away and have no right to make mistakes.
