China lunar calendar can be counted. Do foreigners who use the new calendar know which day of each month is the full moon?

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.

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 were very serious political events in ancient China.

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.

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.
