Shō Shitsu
A number of major reforms were effected in the final years of Shō Shitsu's reign , primarily at the guidance or suggestion of Shō Shōken , who was appointed "sessei" , a position which has been compared to prime minister , in 1666 . Shō Shōken also compiled the "Chūzan Seikan" ( "Mirror of Chūzan" ) , the first history of the kingdom , at the king's orders .
