Excuse me, who can tell me which constellations are opposite and which is the longest over Hunan Province?

In fact, in ancient China, it was believed that the stars in the sky correspond to the regions on the ground, that is, each constellation in the sky corresponds to a certain region on the ground. Or maps and sky maps.

To say that a place is between bullfights does not mean that there are fights and cows (all stars) on it, but that the sky area corresponding to this area is between bullfights.

The so-called "there are columns in the sky and States in the land." That's what it means.
