On February 2 nd, what does the dragon mean by looking up?

In ancient China, twenty-eight nights were used to indicate the positions of the sun, moon and stars in the sky and to judge the seasons. In the twenty-eight lodging houses, the horn, sound, rafter, room, heart, tail and dustpan constitute a complete dragon constellation, among which the horn is like the dragon's horn. After the spring breeze in February, the "Dragon Horn Star" appeared from the eastern horizon at dusk, so it was called "Dragon Head Up".
