The Wei and Jin Southern and Northern Dynasties Zhiwei novel "The Book of The Collected Remains" Volume 1 records the Three Emperors and Five Emperors in the ancient period, and there is a passage when introducing the Cu Clan (Fuxi): (Divine Mother) was born in the twelfth year of the calendar... Or as the human being: The year of the stars is twelve years a week, and the present leaf is the time of the day. Translated into the vernacular, it means that his mother gave birth to him twelve years pregnant, and Jupiter orbited the sun for twelve years, and his birth coincided with the laws of the operation of the heavenly path.
Reading this, you can't help but check the information, how long does Jupiter circle the sun? The precise answer is 11.86 years, and you will marvel at how the ancients observed celestial bodies, especially in antiquity. In fact, the ancients did not have telescopes, and began to observe planets with the naked eye thousands of years ago. In 48 BC, the ancients witnessed with the naked eye the explosion of a new star about 160,000 light-years away, and the situation at that time was recorded in the Book of Han: in April of the first year of the First Year of the Han Dynasty, the guest star was as large as a melon, green and white, and the second star in the east of Nandou, which could be four feet east.
The ancients built a stargazing platform to observe the celestial phenomena, expressing their reverence for the mysterious universe, but in fact, it also implied the exploration of the unknown life. Without astrological observation, there would be no calendar, and agricultural production would inevitably be affected. Guo Shoujing of the Yuan Dynasty used the principle of small hole imaging, using the Gui table and improving the Gui table, when the sun, beam, and small hole were three straight lines, a spot of light could be seen on the Gui surface, that is, the image of the sun, and he calculated the "Chronological Calendar" to calculate the length of the return year. In addition, there are sundials, missing engravings, etc.
In October 1995, members of the Sino-Japanese expedition found a piece of brocade in an ancient tomb at the Niya site in Minfeng County, Hotan Region, with eight seal Chinese characters: "Five stars out of the East to benefit China", indicating the ancients' prediction of the future situation.
