If it is accepted that the year can be changed after the winter solstice, then the year of Xinhai can have the month of Ji Chou; otherwise, the year of Xin Hai does not exclude the month of Ji Chou, nor does it exclude the month of Ji Chou, then it is impossible for Ji Chou to have Zishui. . If the month of Ji Chou is the month of Xin Chou, then the month of Xin Chou in the year of Xin Hai can arch the Zi Water, but the day of Ji Hai in the Xin Chou month cannot Gong the Zi Water. The arch can only be established if the heavenly stems are the same and the earth branches are separated from each other. Therefore, no matter which method of arranging the year is used, it is impossible to miss two children.
