Introduction to the Prince's Palace: The "Prince's Palace" at the top of Luya Mountain has a couplet: "Xia Ci rains in the middle, Xing Dharma rains in the side." Legend has it that Zhu Yuanzhang's eighteenth son was not sealed because he was not sealed. In a fit of anger, he left the capital and became a monk. He preached and preached in the northwest of Shanxi Province, advising people to put agriculture first, so that they could have enough food and clothing. In order to commemorate the prince's great merits and virtues, the world chose to build a prince palace at the top of Luya Mountain. Regarding the origin of the "Prince Hall", there is another local saying that this temple was built for Rahouluo, the prince of the Buddha Sakyamuni. In the Luya Mountain area, there were 72 temples of various sizes during the Ming and Qing Dynasties. In the past, when there was drought and no rain, villagers would go to Luya Mountain to burn incense and make offerings and pray for rain.
