Daoists dedicate days to the Three Officials (or Officers or Rulers), whom CCT call Shun, Yao, and Yu, on the fifteenth days of the first, seventh, and tenth lunar months. Their days are associated respectively with Heaven, Earth, and water. The Heavenly Official, Shun, ranks highest and remains very popular in Taiwan, for example. The Water Official, Yu, is celebrated for having saved the world from uncontrolled flooding. Three Daoist deities considered at the pinnacle of the pantheon are known as the Three Primordials. Their festival days coincide with those of the Three Officials, respectively, the first two of which also coincide with the CCT Lantern Festival and Ghost Festival.
