In the history of Qing Dynasty, the garden was repaired by Sheng Xuanhuai and his father. It was completed in Guangxu two years ago. When the garden "Jiashu Rong and beautiful flowers thrive, exotic stones show clear circulation, balcony Suiyuan Hall, wind Pavilion and moon pavilion, high and low, belong to each other" (Yu Yuyu's work "Records of Remembering Gardens"). Because the former owner's surname was Liu Yuan, Sheng's family name was Liu Yuan, which was changed to Liuyuan by its pronunciation. Today, Guanyun Peak at Guanyun Pavilion in Liuyuan is really the best of the Taihu Stone. It is a collection of four wonders "thin, wrinkled, leaky, penetrating" of the Taihu Stone. It is said that its value has reached 80 million yuan. Legend has it that this wonder stone is still a relic of the Flower and Stone Class in the late Song Dynasty.
