The Xia Dynasty determined the four seasons by observing the positions of four stars in the southern sky at dusk. What's wrong with this sentence?

If you give me a judgment about this option, I must have chosen the right one. The following answer is purely sarcastic.

According to the archaeological findings of Yangshao culture and Hemudu culture, at the latest in 2520 BC, our ancestors have systematically observed Ziweixing (Arctic Samsung) and Great Mars (Antares Samsung), and it is natural to determine the seasons in turn. Judging from the speed of cultural development, it should be taken for granted to systematically observe some bright stars in the four seasons of the Xia Dynasty.

So what's the problem? Here comes the word picker. Observing the position of the stars in the "southern sky", how to explain it? Since it is due south, the bearing is determined. Only declination determines the position of the stars. Regardless of the precession of the earth's axis, it always appears in the same position due south all year round.

Well, sophistry ends here, but at least it can be demonstrated and refuted. If you change the location to "time", this option is right. Again, just sarcasm. When introducing people to the development of ancient astronomy, I will say this. ...
