to a new building known as the Poolside House in 1966 at the start of the Cultural Revolution. After Mao's death, the Chrysanthemum Library was preserved as a museum which is not accessible to the general public. Immediately to the east of the Library of Chrysanthemum Fragrance are a series of buildings known as the West Eight Houses (), which served as a dormitory for Mao's personal aides and secretaries. Shuqingyuan Pavilion () Located in the northeast corner of the Southern Sea, the building was built for the Qianlong Emperor as part of a small garden, similar in style to the Beihai Park. After 1959, the original building was destroyed in order to make way for the construction of a barracks and officer staff quarters for Unit 8341, the Zhongnanhai security guard regiment. The formal address of Shuqingyuan Pavilion and the surrounding complex of buildings used by Unit 8341 is 81 Nanchang Street, Xicheng District, Beijing. Building 202 (Chinese: 202别墅) The building next to Huairen Hall was constructed in 1974 as a specially reinforced earthquake shelter. Mao Zedong was relocated here from Poolside House after the July 1976 Tangshan earthquake. Mao died in this building on September 9, 1976. West Four Houses () These four houses were built as part of the western wing of the Huairen Hall complex. They are also known as Qingyuntang (). These buildings were acquired by the Peking Institute of Historic Research after the end of the Beiyang government. After 1949, the Propaganda Department was located here before it was eventually moved to its current headquarters on 5 West Chang'an Street. Several communist party leaders also lived in these buildings including Deng Xiaoping, Li Fuchun, Chen Yi and Tan Zhenlin. During his paramount leadership, Deng Xiaoping used his home as a meeting place for informal conferences that would include members of the Central Advisory Commission, the Politburo, the Secretariat and the party elders. It was in Deng's home that the decision was made to use force against the demonstrators during the 1989 Tiananmen Square protests and massacre. Wanzi Gallery () The original buildings in this area were built by the Qianlong Emperor in 1742 to celebrate his mother's 50th birthday. Though the Qing-dynasty era buildings in the area no longer exist, this narrow lane in south-western Zhongnanhai where they once stood is now lined with houses that serve as residences of party leaders.
