Introduction to Dongying Temple: Dongying Temple was founded in the Ming Dynasty. The existing buildings were rebuilt during the Daoguang period of the Qing Dynasty. The main buildings include the mountain gate, the offering hall, and the dormitory hall, with a total of more than ten buildings and thirty-three rooms. The style is simple and clear, simple and simple with few carvings, which reflects the "magnificence of the heaven" and the simple and unpretentious spiritual realm of "Martial Saint" Guan Yu. It was a barracks that used to guard the city. It was one of the five camps in the city and had a temple dedicated to Guan Yu. In September 2003, it was announced as a key cultural relic protection unit in Shaanxi Province.
