A good place to overlook Beijing. In ancient times, Jingshan and Beihai were the old roads of Yongding River. The river where Jingshan is located is higher, and it gradually becomes a mound after the Yongding River is rerouted. When the Liao Dynasty Yingjian Tongyu Palace (now Qionghua Island in Beihai Park), the remaining soil was piled up here. In the 19th year of the Jin Dynasty, Jin Zhangzong built Taining Palace on the south side of the place, chiselled Xihuatan (now Beihai), piled into small hills here, built a royal garden, known as "Beiyuan". Its mountain is surrounded by two walls, and the mountain is built in the Guanglou, known as one of the 12 scenes of Jinzhongdu.
