Introduction to the Kaishan Old Temple: The Lion Zhengzong Zen Temple was destroyed by war twice in the late Yuan and early Ming dynasties. After the Zenyuan Temple was built in the early Qing Dynasty, the incense was moved to the foot of the mountain, and the old site was called Kaishan Old Hall. In the 17th year of the Republic of China (1928), Xu Shichang inscribed "Dashu Hall". In 1985, Ye Qianyu handwritten the name "Open Mountain Old Palace" on the forehead.
