The yin and yang of the heaven and earth are determined by the stems and branches, and the eight trigrams are derived from the zodiac signs. The Taoist Three Purities decreed the twelve star kings to control the misfortunes and blessings of the world and control the yin and yang of the three realms. They adhere to the mysteries of the Eight Diagrams of the Book of Changes, inherit the good and bad luck of the sixty-four hexagrams, and follow the mysteries of the directions of the nine palaces. From teaching Taoism in the prehistoric times to conferring gods in the Shang and Zhou Dynasties, from establishing religion in the Qin and Han Dynasties to protecting Taoism in the Ming and Qing Dynasties, in the long history of China, they have guarded the integrity of Taoism and protected the peace of the people. The depth, the facts of Chinese history, the wonders of ancient mythology, interpret the thousand-year destiny of the twelve zodiac star kings from their birth to becoming gods, from protecting Taoism to conquering the world...
