The main attraction of Yong'an Temple is the water and land murals, which depict elements of heaven, earth, and the human world, Buddhism, Confucianism, and Taoism. The Five Sacred Mountains, the heroic women, the sages, the holy monks, the hellfire, and the Ten Great Vidyarajas are all depicted in the main hall. The most classic one is the "Face-tearing Vidyaraja", which tears off its terrifying face to reveal its compassionate true face.
