February 27th of the lunar calendar in the year of Renyin, when it is ugly.
Ren is 7, the upper divination is 7+2+27=36 36/8, and the remainder is 4, which is an earthquake divination.
The next hexagram is 7+2+27+2=38 38/8, and the remainder is 6, which is a divination.
Therefore, when the year of Renyin is over and the day of Xin Si is ugly, the female life is a divinatory image of thunder hydrolysis.
