What does it mean to move the fly ash pipe and turn the bucket around?

Burning fly ash pipe means burning reed film into ash, putting it in the twelve-music gauge pipe and burying it underground in the secret room. The upper end of the pipe is flush, covered with silk, and the lower end is of different lengths, all of which are buried in the soil. Huang Zhong, the longest manager, was the first to get Yang into the field. When the winter solstice returns to the sun, the dust from the yellow bell tube will fly out automatically, which is called "fly ash weather method" by the ancients.

On the winter solstice, the handle of the Big Dipper points to the north, and as the day begins to get longer, the night begins to get shorter. The handle of the Big Dipper began to move eastward gradually.

Actually, it's not interesting. I just want to say that today is the solstice of winter, and the days are getting longer and longer. Yang has returned to the earth.
