In ancient China, the calculation of solar calendar by lunar calendar was invented by foreigners, didn't it mean that lunar calendar was not allowed? But when it comes to our thousands of ancestors, you have miscalculated. In China, the lunar calendar is a combination of yin and yang, the 24 solar terms are a solar calendar, and the first month of the lunar calendar is a lunar calendar. The solar calendar is the main part of the lunar calendar, and the agricultural season is guided by the 24 solar terms, not the month.

In fact, the lunar calendar is of little use to ancient agricultural production. The calendars of major countries are all solar calendars with similar contents. After all, we are all facing the same earth.

By the Ming and Qing Dynasties, China's astronomical calendar was really behind the times, even behind the previous generation in many aspects.

I personally think there are institutional reasons. Tianxue served the imperial power and never developed into a real astronomy.

On the other hand, the connection between Tianxue and divination and fortune-telling is too close, and the mysticism tendency is too strong, which leads to many important technologies and knowledge being preserved as state secrets and not handed down during the regime change. So each generation either overturns the technology of the previous generation, or it can only be worse than the previous generation.

What is said above is not easy to understand. Explain briefly.

The astronomical institutions in ancient China, such as Qin, were calendar compilers and royal fortune-telling institutions, whose main task was to provide legitimacy for imperial power by explaining fate. Why is the emperor you? Because of fate. Heaven conveys the destiny to the world through various methods, the most important of which is the astronomical phenomena. Astronomers need to predict the astronomical phenomena, explain the destiny, and let the emperor make the necessary political gestures. Major astronomical phenomena are very serious political events in ancient China, such as:

Record of Emperor Shen Zongxian, Volume 6

On the night of the third day of October, the guest star saw the northeast, and ... I was afraid to see it in the palace and prayed for it at night.

This thing is about the supernova explosion of the crab nebula. Emperor Wanli of Ming Shenzong heard that a star suddenly appeared in the sky. He ran out in the middle of the night and knelt down directly to God. Because the sky is fate, God suddenly came up with something, and I don't know why. This requires an explanation from an astrophysicist: God thinks that the emperor is not doing well and wants to warn you. I wish I had changed it. However, if an astroscientist comes to say: a new star appears, which means that fate has changed and Daming Mountain is almost finished. Then maybe someone will really rise up and resist. On the other hand, the dynasty changed and the new emperor ascended the throne. He also needs an astrophysicist to explain what celestial phenomena appeared on a certain day in a certain year, that God instructed me to be emperor.

Since astronomers are so important, astronomical phenomena and calendar calculation techniques and methods are so important, both of them are baby bumps and need close attention. Therefore, the laws of past dynasties have clearly stipulated that celestial scientists are absolutely forbidden to make friends with ministers, and celestial technology is absolutely forbidden to spread abroad.

That's good, because China had a strong national power in ancient times, but in the prosperous times, it met a successful emperor and found a group of talented astronomers, so it was possible to compile a very accurate calendar. But in a few years, the emperor changed, or the dynasty changed a generation. The new emperor wants to break the old and establish the new, and the older generation of astronomers have run away, been clicked, or stood aside to support the elderly. Replacing the calendar with a new group of astronomers may be worse than the previous generation.

The ancient calendar of China is like this. Not all of them are good or getting better and better, sometimes they are good, but the new calendar will soon be poor. It will be better in a few hundred years, and it will be poor in the next few hundred years.

China experienced a catastrophe in the late Yuan and early Ming Dynasties, and it was also a catastrophe in the late Ming and early Qing Dynasties. A lot of knowledge is lost, and Tianxue, as an important national secret, bears the brunt.
