What astronomical phenomenon is that dogs eat the sun? What is the reason for it?

It used to be a superstition that dogs eat the sky. People believe that major events and even disasters will occur during solar and lunar eclipses. In the past, the solar eclipse was called Tiangou Food Day in ancient China. From the Spring and Autumn Period to the Qing Dynasty, China recorded more than 1000 solar eclipses. The ancients believed that all natural phenomena were providence, and some abnormal phenomena indicated that something important was going to happen.

There was a solar eclipse, which may be related to the emperor, or the emperor did something wrong, or the government was unclear, and so on. Remind everyone that there will be a solar eclipse. These phenomena are related to the monarch, and if the monarch does not correct them, there will be disaster. In feudal society, the monarch was the master of the country. If the monarch has a disaster, so will his people. When there is a solar eclipse, people will hold a ceremony to pray for the early end of the eclipse. In ancient times, the imperial court also made many prayers. The emperor had to worship heaven and earth and pray for his people.

There are records of solar eclipses in China's early Oracle Bone Inscriptions, but these records are quite mysterious, and there is no exact date. In ancient China, people thought that the sun had been swallowed up. People believe that dragons eat the sun, and people will beat pots and pans to drive them away. More importantly, China people have learned more about astronomical phenomena. With the further development of astronomy, people have more understanding of normal phenomena such as solar eclipse and lunar eclipse, and have some paper records. There are still some people who believe in old stories and try to avoid disaster in some way.

The main feature of an eclipse is the moon. The moon lies between the earth and the sun. It blocks the sunlight. On earth, we see the sun gradually blocked by circular shadows. A solar eclipse occurs in a similar way, but if the earth is between the moon and the sun, it will block sunlight from reaching the moon. Because solar eclipse is a big concept, it also includes total solar eclipse, partial solar eclipse, annular solar eclipse, total lunar eclipse, partial lunar eclipse and penumbral moon. Because the premise of the eclipse is that as long as the new moon and the full moon are in the same line. From our actual observation, the frequency of solar and lunar eclipses is very low, and it does not happen every weather cycle. It can be seen that the key problem lies in the connection of the three.
