As already noted, affairs in the Otherworld are managed by official Bureaux or Ministries very similar to those on earth. The Fêng shên yen i mentions several of these, and gives full details of their constitution. The first is the Ministry of Thunder and Storms. This is composed of a large number of officials. The principal ones are Lei Tsu, the Ancestor of Thunder, Lei Kung, the Duke of Thunder, Tien Mu, the Mother of Lightning, Feng Po, the Count of Wind, and Y[’u] Shih, the Master of Rain.

These correspond to the Buddhist Asuras, the “fourth class of sentient beings, the mightiest of all demons, titanic enemies of the Dêvas,” and the Vedic Maruta, storm-demons. In the temples Lei Tsu is placed in the centre with the other four to right and left. There are also sometimes represented other gods of rain, or attendants. These are Hsing T’ien Chün and T’ao T’ien Chün, both officers of Wen Chung, or Lei Tsu, Ma Yüan-shuai, Generalissimo Ma, whose exploits are referred to later, and others.
