The origin of trunks and branches

Yue Ji, the main branch, developed from the twelfth lunar month. According to the meaning of the five elements, "Big Noisy" adopts the feelings of the five elements and is made by a bucket machine. Party A and Party B are called dry when they are famous every day, and ugly when they are famous every month. There is something in the sky that uses the sky, and there is something in the ground that uses the moon. Yin and Yang are different, so there are branches and branches. "So you can know that at the beginning of the invention, stems and branches were used to record the sun, and branches were used to record the moon.

In ancient times, the moon was built as early as the twelfth birthday. When we understand the movement of the sun, the moon and the five stars from the perspective of the clock plate, we can clearly see that the moon is the old position when the sun and the moon meet. The ancient calendar chooses the winter solstice and the day when the sun and the moon meet (new moon) as the corresponding scale of "Zi";

The hand of the moon has circled for more than 27 days, but at this time, as the annual hand of the sun's apparent movement, it has moved forward by about a scale, and it needs to move forward for more than two days to catch up with the sun for the meeting between the sun and the moon. At this time, they will meet on the "ugly" scale, so that the encounter between the sun and the moon will gradually occur on twelve scales, thus determining the structure of the moon.
