The rules include not only the complete procedures to construct the three-powered interpolation used by Shoushi Computus in calculating the solar, lunar and planetary equations of center, but also the detailed routines, namely the Geyuan Shu (the procedure of circle division), to derive the table contained in the Shoushi Computus for transferring the pseudo-ecliptic longitudes of the sun into equatorial coordinates, which turns out to be compatible with the results obtained with spherical trigonometry.
