On another occasion the main Wang Yeh of the Five was on his way to Hsikang in central Taiwan on a tour of inspection when he encountered a demon causing trouble. He had gathered together a large force of spirit soldiers from the Underworld and was causing great hardship and harm to the local people. The Wang Yeh summoned the other four Wang Yeh and, with help from Kuan Yin, the local City God, and the Ma Tsu from Peikang, he defeated the demon and his army but suffered a wound to his head.

Divining blocks are used however when temple committees wish to ascertain the views and wishes of Wang Yeh concerning his personal circumstances such as the location or use of his images.
Pestilence Wang Yeh are not approached for aid and advice as are, say, agricultural or fertility deities. Their role is limited to protection, and by extension to cures from pestilential diseases. They are, however,
