With the help of Feng Xiaobao, a monk at Luoyang White Horse Temple, he found a book of "Dayun Sutra", which read "Maitreya is a queen and a domination of the world". They used these words to promote the "Yi Shi Revolution", saying that Wu Zetian is "Maitreya, contemporary Tang Dynasty master of the Futi master". So they changed Tang to Zhou, became a female emperor, and the two Beijing states built Dayun Temple, recited the Dayun Sutra, and preached "God of King Power". For a time, Dayun Temple was built in all the counties of the country. Shangzhou belonged to the "place of Beijing and Chang'an in the west", and the Dayun Temple was quite spectacular. It was facing Danjiang in front, and Jinfeng Mountain behind it, half in the city, half outside the city; the name of the temple outside the city, the name of the temple in the city.
