How did the order of gossip and heavenly dryness come about when six hexagrams were installed?

In fact, it is the change of the moon, which can be seen in the Book of Changes. The full moon is dry in May, the moon is dark in March, there is a slight earthquake in March and April, and it is against the moon in July and August. After the fifteenth month, it began to be short, about eighteen days, twenty-three days, and the ridge was the hub of the lift, which was called the merit of Wuji.

Na Jia, that is, putting heavenly stems on gossip, the moon rises in the west and then rotates in the order of northwest and southeast, which is different from the order of the sun in the southeast and northwest. And the moon is only half in the sky, only southeast and west, and the north is empty. 1 month 15, the moon starts from the east, goes to Naga, Xun Na Xin, and then goes west, and Gennabc is in the south. It's cloudy after 30, so it starts from B, in which the vacancy of nonyl is matched with Gankun, indicating that the ending echoes satisfactorily.
