Extended information:

The dragon's rising head is a reflection of the seasons in China's ancient farming culture, which originated from the worship of natural phenomena and was related to the understanding of the operation of stars in ancient astronomy and farming culture. The ancient astrological culture in China has a long history and is profound. The ancients began to explore the mysteries of the universe very early, and thus deduced a complete and profound stargazing culture.

The purpose of ancient people's observation of celestial phenomena is to determine the time, thus providing services for agricultural production. Although the "Dragon Rise" has a long history, it was widely circulated as a national festival and appeared in the literature after the Yuan Dynasty. In the Yuan Dynasty, "the second day of February" was called the day when the dragon looked up.

As February of the lunar calendar has entered the mid-spring season, "February 2" is between the "rain", "fright" and "vernal equinox" of the 24 solar terms.
