More than 2,000 years ago, Ji Bo, the mother of Emperor Liu Heng of the Western Han Dynasty, took a bath in the hot spring and built a palace in the southeast of the hot spring. Now Jibomiao Village in the southeast of the hot spring is the seat of her palace, and the mountain in the north of the hot spring is named Niangniang Mountain because of its tour. In the Western Han Dynasty, in order to facilitate the emperor and dignitaries to bathe and have fun, Guangcheng Garden was specially built near the hot springs, and it was also built in the Eastern Han Dynasty. There are "more than 100 pagodas, many corridors in the garden, secluded winding paths, ancient vines and brilliant green flowers." Especially after the capital of Luoyang was established in the Eastern Han Dynasty, officials were specially set up in hot springs to take charge of reception. Liu Zhuang, Andy Liu Hu, Shun Di Liu Bao, Huan Emperor Herry Liu, and Eastern Han Emperor Lingdi Liu Hong all bathed in hot springs many times. After enjoying the joy of the shrine, they went to Guangcheng Garden to rest and hunt. In the early years of Yongben, the royal regime in the Eastern Han Dynasty was in turmoil, and Guangcheng Garden was in ruins, ending its historical mission.
After Emperor Yang Guang of Yang Di acceded to the throne, he heard that Guangchengze (now Jianshan Reservoir) is not only a good pasture with "a hundred miles around and overgrown with weeds", but also a "magical soup coming out" for bathing and fun, so he opened a pasture here to graze a famous horse that is said to be "sweating like rain, stepping on stones can rot".
