What's the use of _ before constellation?

Which dynasty was the constellation introduced to China?

Constellations are familiar to many people so far, and now constellations are used in some personality and numerology analysis in our lives. But a long time ago, in distant ancient times, there were already records of constellations. 12 constellation originated in Babylon. At that time, Babylon began to divide the ecliptic of the sun from the vernal equinox, and it was divided into 12, each of which was called the palace, also known as the ecliptic 12.

At the beginning, the zodiac 12 belonged to the category of astronomy, which was used to identify the direction. With the spread of Daogong 12, it gradually spread to ancient Greece. But according to the needs of geographical location, the ancient Greeks needed to sail around. They had to have more accurate astronomical knowledge, and their astronomical level was improved to some extent in the ancient culture of Babylon. The Greeks integrated 12 Daogong with more accurate astronomical knowledge in navigation. On this basis, the ancient Greeks combined the Taoist temple of 12 with Greek mythology, and gradually formed the concept of 12 constellation, and correspondingly derived some judgment systems in numerology and personality, which gradually formed a part of Greek culture.

With the formation of the myth of 12 constellation, after a certain period of time, the Greek 12 constellation slowly spread to India, and Indians gradually absorbed Greek astronomy, constellation legends and Buddhism on the basis of the original Babylon.

The document "Dafang Waiting for the Sun" in the Sui and Tang Dynasties was translated from an Indian monk, which also involved some astronomical, geographical and calendar contents, including some Indian constellations with Greek astronomical concepts, which were also introduced to China at this time. It can be said that the constellation 12 was introduced into China at this time.

Many translated words in these Buddhist scriptures have a certain influence on the name of today's 12 constellation. Before 1000, we had a complete concept of 12 constellation in China. In the late Qing Dynasty, Kang Youwei identified the name of 12 constellation as some familiar styles.
