Yiyuan was built in 1874 1882 in the late Qing Dynasty. Gu Wenbin, Ningshaotai Road, Zhejiang Province, built a nine-year-old residence in Wukuan, Shangshu, in the Ming Dynasty. It consumed 200,000 yuan of silver and took the sentence meaning of "Analects of Confucius" "Brother Yiyi" and was called Yiyuan. The garden is divided into two parts: the East and the west. The west part of the garden is an ancestral temple, and the south part of the garden is a residential building. Because the garden was built late, it absorbed the directors of various gardens, such as Fulang, Mandarin Duck Hall, rockery, Shiqiang, etc.
