"The following circle (VII) is divided like the VIII and XI into twenty-four divisions, each division representing one of the twenty-four solar terms or twenty-four periods corresponding to the day on which the sun enters the first and fifteenth degree of one of the zodiacal signs. This circle is therefore a miniature calendar, and its use is to determine the season during which a house may be erected or a tomb built in any given place. These twenty-four seasons being however not only under the influence of the sun, but also under that of the five elements and the five planets, the next two circles exhibit the influence which these elements and planets exercise on each of the twenty-four seasons of the year."
