In 1955, Rong Yiren donated whole garden (except for the private mansion) to the country. In 1960, the garden expanded to Mt. Hengshan of Wuxi, making its area more than 860 acres. In 1994 the garden was listed as "Wuxi heritage protection unit". In 2006 it was listed as "Major Historical and Cultural Site Protected at the National Level".
