Introduction to Tianwang Hall: Tianwang Hall is the main hall of the temple. The four heavenly kings and Maitreya Bodhisattva are enshrined in the hall. Because the "Dayun Sutra" said that Maitreya was reborn in advance to save all living beings, Wu Zetian borrowed these scriptures to imply that Feng Xiaobao and others advocated that she was the "reincarnation of Maitreya". Therefore, the Maitreya Bodhisattva statue in Dayun Temple has the characteristics of "male head and female body". There are only two such statues of the goddess Maitreya Bodhisattva in the country, and the other one is located in Longhua Temple in Shanghai.
