When was Shihai?

In ancient China, a day was divided into twelve hours, and each hour was equal to two hours now. According to legend, the ancients named each time according to the time of animals in the zodiac.

This is the twelve-hour system used in the Western Zhou Dynasty. In the Han Dynasty, it was named Midnight, Crow, Pingdan, Sunrise, Food Time, Horn, Japan-China, Sundial, Sunset, Dusk and Man's Decision. It is also expressed by the twelve earthly branches, and it is the child time from 23: 00 to 1 at midnight, the ugly time from 1 to 3: 00, and the Yin Shi time from 3: 00 to 5: 00, which are recursive in turn.

At this time, it was already late at night, and people stopped their activities and had a rest. Calm means quiet. (9: 00 p.m. to 1 1 p.m.). Pigs sleep at night.
