What did archaeologists find in Yin Ruins?

Many caves were found in the archaeological excavation of Yin Ruins, some of which were used to store grain? The bottom and walls of this cave are mostly smeared with grass and mud, and green and gray particles remain at the bottom? It is reasonable to think that the Shang Dynasty formed a natural economy dominated by agriculture, and the calendar mainly served agriculture. Did Shang people have a developed calendar? Among the Oracle Bone Inscriptions, there is the earliest solar eclipse in the world? A record of the eclipse? One of Oracle Bone Inscriptions in Wuding period: "Gengshen, there is food in the moon?"

According to astronomers' inference, an eclipse did occur in the early morning of 65438 BC+0365438 BC+065438 BC1October 24th. So this record is well-founded?

Sixty anniversaries began in Shang Dynasty? Since Wang Hai, the ancestor of Shang Dynasty, Shang people began to use the names of stems and branches? In the Oracle bone inscriptions in Yin Ruins, 60 branch tables were found. Businessmen take 10 as ten days, and on the last day of every ten days, it will last ten days. In the calendar of Shang people, the moon is once a month, and the size of the moon is different. Businessmen take1February as a year, and there are leap months?

The calendar of Shang dynasty has been divorced from the simple lunar calendar, but a combination of yin and yang? The lunar calendar takes the moon's profit and loss once as January; The solar calendar takes the earth around the sun as a year? In this case, if there are only 12 months in a year, there will be a gap of about 10 days every year?

The solution of Shang people was to set up a leap month after a certain year and put it at the end of the year? In Shang dynasty, people set leap, once every three years, twice every five years, and finally used the method of 17 years?

Oracle Bone Inscriptions called a year a year of sacrifice because Shang people were superstitious and held sacrifices every year? The word "year" in Oracle Bone Inscriptions is similar to the word "season" now, with the word "grain" above and the word "person" below, as if a person was carrying a bundle of grain, symbolizing the annual harvest?
