What is the origin of the dragon's rise on February 2?

The rhetoric of "dragon heads up" comes from ancient astronomy. In ancient times, people chose 28 groups of stars near the equator of the ecliptic as coordinates as reference objects for observing astronomical phenomena. According to the orbit and position of the sun, moon and stars, the ancients divided the astrology near the ecliptic into 28 groups, commonly known as "twenty-eight hostages".

"Accommodation" means to live, because they are surrounded by the sun, the moon and the five stars, much like the place where the sun, the moon and the five stars live, so they are called "accommodation". The "Twenty-eight Hostels" are divided into four groups according to the four directions of east, west, north and south, resulting in "four elephants": black dragon in the east, white tiger in the west, suzaku in the south and Xuanwu in the north.

The seven nights in the East are called "Jiao, Kang, Earth, Fang, Xin, Wei and Ji Pan", which form a complete dragon-shaped astrology. People call it the "Oriental Black Dragon", in which the horn lodge represents the dragon's horn, Kang lodge represents the dragon's throat, Di lodge represents the dragon's claw, Xin lodge represents the dragon's heart, and Wei lodge and Jisu lodge represent the dragon's heart. In winter, the seven nights in Black Dragon are hidden under the northern horizon.

In mid-spring (between the vernal equinox and vernal equinox), arcturus (one star and two stars) appears on the eastern horizon. At this time, the whole body of the black dragon was still hidden below the horizon, but arcturus appeared first, so it was called "Dragon Looking Up". The rise of the dragon refers to the looming change of the black dragon and seven stars in the sky, not the real change of the beast dragon.
