Fortune telling should continue _ those things that come true.

Why do you count three days as one year when you push your fortune?

To be exact, one hour is worth ten days.

Twelve hours a day is 120 days, which is 4 months.

Three days is 12 months, which is one year.

Here's my guess:

In ancient times, a day was divided into 100 hours, and in Qing Dynasty, it was officially designated as 96 hours, and each hour was divided into 8 hours.

Although we don't need to continue to row branches, we can continue to divide branches into twelve equal parts. A moment is regarded as twelve branches, and each branch is divided into ten days, totaling 120 groups. Eight minutes is 960 teams. Think of this group as Artest. If we push back, these 960 groups are equivalent to 960 minutes, which is ten days.

In addition, there is a tool "missing engraving" in ancient timekeeping. Leaky pot Because the arrow of the clepsydra is engraved with symbols to indicate time, it is called clepsydra. "Six Divisions": "It is sometimes wrong to make it clear about the war." Han Shi's Aidiji: "It's 120 degrees short." Yan Shigu's note: "The old leak 100 score is increased by 20 points today." Liang Huijiao's Biography of Becoming a Monk Explaining the Ancestor of the Southern Dynasties: "There are no missing carvings in the mountains, and there are twelve hibiscus leaves in spring. Because of the current and waves, it is set at twelve o'clock, and there is no difference between the shadows. " Song Pengcheng's "Mo Ke Dao Xi" Volume 7: "The China Dynasty put astronomical places in a ban, and set up leaky sculptures, rooftop views and bronze armymen, all of which were like supervisors and mutual inspections."

It says here that a day and night is 120, but from the unearthed cultural relics, a pot of water is at most one hour, so this 120 is not a day and night.

Copper leakage in Mancheng

Mancheng Copper Leak 1968 was unearthed in the tomb of Liu Sheng, Zhongshan King of the Western Han Dynasty in Mancheng, Hebei Province. Liu Sheng, the son of Emperor Jing of the Western Han Dynasty, died in four years (i.e. 1 13 BC). Therefore, it is considered that this copper leak should have been made as a funerary object before 1 13 BC, and now it is collected in the Institute of Archaeology, Chinese Academy of Social Sciences.

Copper leakage is cylindrical, with three legs at the bottom and a height of 22.4 cm. There is a small tube outside the pot body near the bottom, which has been broken. There is a square hanging beam on the lid of the pot, and there are opposite rectangular holes on the lid and hanging beam for inserting a ruler engraved with time. The water in the pot gradually leaks out of the small tube and the ruler gradually drops, so that the change of time can be observed. This is the above-mentioned single pot drainage type arrow leakage. Judging from the height of the pot, the pot is very small. It is estimated that it will take less than an hour or a quarter from a full pot to the end. The displacement in the pot varies from full to shallow, so its timing accuracy will not be very high. It can not be used as an astronomical instrument, but only as a rough time measurement tool in daily life.

There is still a leak, the copper pot leaks.

The clepsydra existing in the Palace Museum in Beijing was made in A.D. 1745. The water leaked from the upper pot flows out from the finely carved Longkou and flows to the lower pot in turn. There is a bronze man on the lid of the pot who seems to report an arrow shaft. There are 96 squares carved on the arrow shaft, and each square is 15. People report the time according to the sign of bronze man holding an arrow shaft.
