During the Cultural Revolution, the mansion was used by the Beijing Air Conditioning Factory until it experienced a revival in the 1980s. In 1982, it was declared a Major Historical and Cultural Site Protected at the National Level in Beijing. Since November 1996, the buildings and the gardens have become a tourist attraction. Renovation works on the mansion were completed on 24 August 2008 during the 2008 Summer Olympics in Beijing.
