How to divide the "six-day seven-point method" in ancient gossip and solar terms

You should be talking about the famous "six-day seven-point method" in Meng Xi in the Western Han Dynasty. This method originated from the acquired gossip, and Meng Qian used the positive four hexagrams (namely, shock, separation, intersection and column) to express the decline of yin in spring, summer, autumn and winter and the growth of yang. Then the remaining 60 sixty-four hexagrams * * have 360 hexagrams, each of which represents one day, and * * * has 360 days. There are 365.25 days in a year, and there is nothing wrong with the remaining 5.25 days. So on May 25th, it was divided into 60 hexagrams on average, with 80 points per day, and on May 25th, it was just 420 points, with an average of 60 hexagrams, with 7 points per hexagram. This is the "six-day seven-point method" to study the laws of solar terms.
