Taking the earthly branch as the month, it was built in January, February, March, April, May, June, July, August, September, October, November and December respectively.

With inaction wood, yin is yang wood, and the base is yin wood.

In ancient times, time was measured by clepsydra;

Leaking pot is divided into two parts: sowing pot and receiving pot. The seeding kettle is divided into two or four layers, both of which have dripping holes, and finally flow into the receiving kettle. There is an upright arrow in the receiving pot, which is engraved with 100 minutes. The arrow gradually rises with the water storage, revealing the number of minutes showing the time. And a 24-hour day and night is 100 minutes, which is equivalent to 1440 minutes now.

It can be seen that each moment is equivalent to the current 14.4 minutes. So "3: 30 noon" is equivalent to 1 1: 43.2 at noon now. In the old novels, there is a saying of "chop at three o'clock in the afternoon", that is, chop at three o'clock in the afternoon (fifteen minutes away from noon), when the yang is at its peak and the yin disappears immediately. This heinous crime should be "not even allowed to be a ghost" to show severe punishment.

Yin and Yang scholars say that Yang is the most abundant, which is different from modern astronomy. It is not the most abundant at noon, but at 3 noon. In ancient times, beheading was carried out in different periods, which means beheading is very important.

Generally, beheading is to operate at noon to make it have a ghost to do; Repeat or heinous crimes, you must choose to operate at 3: 00 noon, don't let it be a ghost. The meridian gate of the imperial city is also the most prosperous, regardless of time, so the emperor ordered the people who started the meridian gate to behead, and there was no ghost to do it.
