The JADE-EMPEROR, formerly his assistant, is now his co-ruler.
LING-BAO-TIAN-SONG is High Pure or Highest Holy One in the Heaven of Shang-Qing. He does magic writing, calendars and calculators.
LAO-JUN, Supreme Pure or Greatest Holy One, is in charge of Immortals in the third Heaven of Tai-Qing and leads the way to ‘The Way’.
