There were no telescopes in the Tang Dynasty, so how did they find the Moon Pit?

As we all know, among many dynasties in China, the Tang Dynasty was undoubtedly the most powerful one. This power is reflected in all aspects of social development, including science and technology, humanities and economy. Here's an interesting question. As early as the Tang Dynasty, the working people in our country had discovered that there were pits on the surface of the moon, and now people are also very curious about this problem. That's from ancient China. How did they find this interesting phenomenon?

Although in the Tang dynasty, people could not make modern telescopes, because the scientific and technological strength at that time could not support the manufacture of such advanced telescopes. But we know that although it is not as developed as modern technology, our ancestors can still make some telescopes with lower multiples. But at that time, it was just a plaything in the hands of princes and nobles.

Another important point is that although we usually think that the distance between the moon and us is the same, it is actually different. When the moon rises to the sky, it is the closest time to us. Now, in some places where the observation position and weather are good, we can see the "crater" on the surface of the moon with the naked eye. It is conceivable that in ancient times, people could see the surface of the moon more clearly without pollution.

In ancient times, almost all emperors were interested in astronomical phenomena and thought they were the sons of heaven, so they spent a lot of energy and manpower to observe the astrology. It is not surprising that in some specially set institutions, they had slightly advanced tools at that time. Therefore, it is not surprising that we can see the potholes on the moon.
