North is the child position, south is the noon position, east is the base position, and west is the unitary position. Day and night, the sun moves in the direction of 12 and returns to its original place, thus creating the concept that the sun is located in one hour, and a day and night is 12 hour, so people can use the position of the sun in the sky to determine the time.

This timing method has been accepted by people and is still in use today. In the biography of Yongfeng in the Han Dynasty, there is a saying that the sun added Shen in the first year of the Yuan Dynasty, which means that the sun was applied for Shen, and then it was further simplified to "noon". , and named after the twelve earthly branches.

In addition, people also use more vivid nicknames, such as "Midnight, Cockcrow, Pingdan, Sunrise, Eclipse, Corner, Daylight, Sunset, Dusk, People Decided", which correspond to twelve o'clock, such as Zishi, Ugly Time and Yin Shi.
