What does Tiangou Food Day portend?

Tiangou food day indicates an unknown omen. China's ancient science and technology were underdeveloped, and many things could not be solved scientifically. Therefore, the ancestors who advocated the gods of heaven and earth invented some strange cultures, such as divination and astronomical phenomena. In ancient times, dogs eating the sun suggested ominous signs. The ancients thought that if this phenomenon happened, it would indicate that the world was in trouble.

Today's "Tiangou Food Day" is called the total solar eclipse. Total solar eclipse is a kind of solar eclipse, that is, an astronomical phenomenon in which sunlight in some parts of the earth is completely blocked by the moon.

Total solar eclipse can be divided into five stages: initial loss, eclipse, eclipse, light production and recovery. Because the moon is smaller than the earth, only people in the umbra of the moon can see the total solar eclipse. Now people call it "the dog eats the moon", which is a unique natural phenomenon.

Significance and value of tengu eating the sun;

The main reason why the total solar eclipse is paid attention to is its great astronomical observation value, because the moon will darken the original dazzling sun and expose the corona layer that was difficult to observe.

Astronomical phenomena such as total solar eclipse have nothing to do with people's daily life. Eat and drink Lazar. However, it represents an ultimate humanistic concern, an extreme love for nature, an eternal curiosity and awe of the iron law of nature that dominates everything, and it inspires all mankind to continue to advance on the road of exploring the universe.
