Participation in the fire is astrology known to ancient women and children. The Xia people have deep reasons for knowing the ginseng. When the ginseng falls to the horizon after dusk and is almost invisible, it is the time when the earth returns to spring. "The farm is busy preparing for farming", it has become an important basis for the teaching of the Xia ethnic group. Around 2400 BC, the fire appeared on the eastern horizon when it was dark in the spring. Its light was like a flame in the east. It attracts people's attention, not only because it is bright, it is like a deliberate fire to light people's hope for seeding. The meaning of "viewing and giving time" in the text is:. ['Observing the sky to arrange time.', 'Observing the sky to engage in farming.', 'Look at the sky to determine the season.', 'Observing the sky to impart knowledge.']
