Introduction to Huangpuyuan: Huangpuyuan was originally the hunting palace of Wan Yanjing of Jin Zhangzong. It was one of the eight major water courtyards in the west of Beijing, so it was also called Shengshui Yuan. It was granted in the second year of Ming Zhengtong (1437 AD) Emiaojue Zen Temple; in the 14th year of Hongzhi (1501 AD), it was renamed Mingzhaodong Ruiyun Temple, commonly known as "Huangguyuan"; in the autumn of 1941, the temple building was burned down by the Japanese invaders, but the temple site, ginkgo trees and ancient stele still exist . The remaining stone tablets in the courtyard are engraved with dragons, turtles and other patterns. The remaining inscriptions prove that Miaojue Zen Temple was moved from the front of Ruiyun Temple in Mingzhao Cave due to the "collapse of the old foundation".
